A go cart engine applies a force of 888N and moves the cart forward 22m.
a) How much work is done?
b) We put on a bigger engine (1111N) but the cart still moves forward 22m. How much work is done now?
c) Why would you put on a bigger engine if you are still moving 22m?
Answer:
Explanation:
a) work=Force times distance. given force is 888N and distance travelled is 22M
work= 888 x 22 = 19536J or 1.954x10^5J
b) work = 1111 x 22= 24442J or 2.444x10^5J
c) putting on a larger engine means that there are gonna be more force applied to the go cart. therefore the cart will travel the same distance faster
a. The amount of work done by the go cart engine is 19,536 Nm.
b. The amount of work done when a bigger engine is used is 24,442 Nm.
c. The reason why a bigger engine is used is, so that the engine can easily do more work in the same amount of distance.
Given the following data:
Force A = 888 NewtonDistance = 22 meterForce B = 1111 Newtona. To determine the amount of work done by the go cart engine:
Mathematically, the work done by an object is given by the formula;
[tex]Work\;done = Force \times distance[/tex]
Substituting the given parameters into the formula, we have;
[tex]Work\;done = 888 \times 22[/tex]
Work done = 19,536 Nm.
b. To determine the amount of work done when a bigger engine is used:
[tex]Work\;done = Force \times distance[/tex]
[tex]Work\;done = 1111 \times 22[/tex]
Work done = 24,442 Nm.

How long will it take an airplane at rest that
accelerates uniformly at 2.5 m/s to reach a ground
velocity of 70 m/s that is required for takeoff
Answer:
28 seconds.
Explanation:
Apply the first equation of motion as;
v=u +at where;
v= final velocity of the plane = 70m/s
u=initial velocity of the plane= 0m/s -----it was at rest
a= acceleration uniform =2.5 m/s²
t= time required for takeoff = ?
Substitute values in the equation as;
v= u + at
70 = 0 + 2.5*t
70 = 2.5t
70/2.5 = 2.5/2.5t
28 = t
Time required for takeoff is 28 seconds.

A container of rocks is brought back from the Moon's surface where the acceleration due to gravity is 162 meters per second if the total mass of the container of rocks is 650 kilograms, what is its weight on
Earth's surface
Answer:
6318 N
Explanation:
From the question given above, the following data were obtained:
Acceleration due to gravity of the moon (gₘ) = 1.62 m/s²
Mass (m) of container = 650 kg
Weight (W) of container on the earth =.?
Next, we shall determine the acceleration due to gravity of the earth. This can be obtained as follow:
Acceleration due to gravity of the moon (gₘ) = 1.62 m/s²
Acceleration due to gravity of the earth (gₑ) =.?
gₘ = 1/6 × gₑ
1.62 = 1/6 × gₑ
1.62 = gₑ /6
Cross multiply
gₑ = 1.62 × 6
gₑ = 9.72 m/s²
Finally, we shall determine the weight of the container on the earth as follow:
Mass (m) of container = 650 kg
Acceleration due to gravity of the earth (gₑ) = 9.72 m/s²
Weight (W) of container on the earth =.?
W = m × gₑ
W = 650 × 9.72
W = 6318 N
Therefore, the weight of the container on earth is 6318 N

What would you expect to see on intrusive igneous rocks compared to extrusive igneous rocks?
Answer:
Intrusive igneous rocks cool from magma slowly because they are buried beneath the surface, so they have large crystals. Extrusive igneous rocks cool from lava rapidly because they form at the surface, so they have small crystals. Texture reflects how an igneous rock formed

We can ignore air resistance.
Answer:
a. 42.92 m/s b 4.4 s c. 915.2 m
Explanation:
Here is the complete question
A volcano erupts, and a chunk of hot magma is launched horizontally with a speed of 208 m/s, from a height of 94 m. We can ignore air resistance.
What is the vertical velocity of the magma when it hits the ground?
Solution
a. Using v² = u² - 2gy since it is motion under gravity, where u = initial vertical velocity = 0 m/s, g = acceleration due to gravity = -9.8 m/s² and y = height = 94 m.
Substituting these values into the equation, we have
v² = u² - 2gy
v² = 0² - 2 × (-9.8 m/s²) × 94 m
v² = 1842.4 m²/s²
v = √1842.4 m²/s²
v = 42.92 m/s
b. We also find the time it takes to drop from the height of 94 m from
y = ut - 1/2gt² , u = 0
So, t = √(2y/g)
= √(2 × 94 m ÷ 9.8 m/s²)
= √19.184 s²
= 4.4 s
c. The horizontal distance the chunk of hot magma covers is thus x = Vt where v = horizontal velocity = 208 m/s
x = 208 m/s × 4.4 s = 915.2 m

A tennis racket strikes a tennis ball with a force of 100 N. With what force
does the ball strike the racket? *
Answer:
-100N
Explanation:
Newton's third law of motion states that to every force exerted on one body, there is an equal and opposite force. This means that if object A exerts an ACTION force on B, there is a force called REACTION FORCE, which is equal and opposite, exerted on A by B.
The action and reaction forces are equal in size/magnitude but opposite in direction. In this case where a tennis racket strikes a tennis ball with a force (action force) of 100N, the ball will strike the racket with a reaction force of -100N.

A player punts a football at an angle of 30 degrees. The football has an initial
velocity of 20.0 m/s. Find the y-component of the ball's velocity.
17.3 m/s
O 10.0 m/s
O 30.0 m/s
0 25.1 m/s
Answer:
The y-component of the ball's velocity is 10 m/s
The second choice 10.0 m/s is correct
Explanation:
Projectile Motion
It's the type of motion that experiences an object that is projected near the Earth's surface and moves along a curved path exclusively under the action of gravity.
Being vo the magnitude of the initial velocity and θ the angle it makes with the horizontal, the components of the initial velocity are calculated as follows:
[tex]v_{ox}=v_o.\cos\theta[/tex]
[tex]v_{oy}=v_o.\sin\theta[/tex]
Since the football is kicked at vo=20 m/s and an angle of θ=30°:
[tex]v_{oy}=20.\sin 30^\circ[/tex]
[tex]v_{oy}=20*0.5=10[/tex]
The y-component of the ball's velocity is 10 m/s
The second choice 10.0 m/s is correct
Birdman is flying horizontally at a
speed of 17 m/s and a height of 78
m. Birdman releases a turd directly
above the start of the field. How far
from the start of the field should the
robot hold the bucket to catch the
turd?
Answer:
68 m
Explanation:
Given that the horizontal velocity of the birdman = 17 m/s and
the height, h= 78 m.
The gravitational force is acting in the downward direction, so it will not change the horizontal speed.
The horizontal speed will remains be constant and will be equal to the initial horizontal speed of the turd.
Initially, the turd was also flying horizontally with the birdman, so the initial velocity of the turd is the same as the horizontal velocity of the birdman, i.e In the horizontal direction, [tex]u_0=17[/tex] m/s.
In the vertical direction, u = 0,
The distance to be traveled, in the direction of application of force, is equals to the height of the turd, i.e
s= 78 m
Let t be the time taken to cover a distance of 78 m.
Now, applying the equation of motion in the vertical direction,
[tex]s=ut+\frac 12 at^2[/tex]
where u is the initial velocity and a is the acceleration due to gravity in the direction of displacement,s.
Here, [tex]a=g=9.81 m/s^2[/tex], so
[tex]78=0\times t +\frac 12 (9.81)t^2[/tex]
[tex]\Rightarrow t^2=(78\times2)/9.81[/tex]
[tex]\Rightarrow t = 4[/tex] seconds.
Hence, the time taken to reach the ground is 4 seconds.
As the horizontal speed, [tex]u_0=17[/tex] m/s, is constant throughout the journey, so
the horizontal distance covered by turd
[tex]= u\times t[/tex]
[tex]= 17 \times 4 = 68[/tex] m.
So, the distance of landing from the start of the field is 68 m as the birdman releases a turd directly above the start of the field.
Hence, the robot must hold the bucket at a distance of 68 m from the start of the field.

Miguel added 150 grams of baking soda to a liter of water at 20 °C. No matter how long he keeps stirring the solution, he can’t get all of the baking soda to dissolve. Explain why.
Answer:
See the answer below
Explanation:
This is because, at 20 °C, the solution has become saturated with the baking soda.
The solubility of a substance is the maximum amount of that substance that will dissolve in a particular solvent at a given temperature. The solubility of a substance generally increases with an increase in temperature.
At 20 °C temperature, the maximum amount of baking soda that can dissolve in a liter of water has been exceeded by Miguel. Hence, no matter how hard he tries to stir the solution, the excess baking soda will not dissolve.
The reason he can’t get all of the baking soda to dissolve is; because at 20 °C, the solution has become saturated with the baking soda.
What is a saturated solution?For us to say a substance is soluble, it means that the maximum amount of that substance will dissolve in a particular solvent at a given temperature. Thus, the solubility of a substance is said increase with a corresponding increase in temperature.
From the question, at 20 °C temperature, miguel has exceeded the maximum amount of baking soda that can dissolve in a liter of water. Therefore, no matter how hard he tries to stir the solution, it will not dissolve due to the excess soda.
