A ball is launched from a slingshot. As the ball travels along its trajectory, what force(s) are acting on it? Select all that apply.
Group of answer choices

Answer:

198m

Explanation:

Distance = speed x time

. d = 330m/s x 1.2s = 396m

This is the distance travelled by the sound from the person to the object and then back to the person. To get the distance from the person to the object, we would have to divide by 2.

. distance = 396 / 2 = 198m

Hi there!

We know that:

[tex]P = \frac{W}{t}\\\\[/tex]

Where:

W = Work done (J)

t = time (s)

We can calculate the work using the equation:

[tex]W = \Delta U = mg\Delta h[/tex]

Plug in the given values:

[tex]W = 60(9.8)(4) = 2352J[/tex]

Now, divide by time:

[tex]P = \frac{W}{t} = \frac{2352}{4.2} = \boxed{560W \text{ (Watts)}}[/tex]

The force of 2812.5 N is being exerted by the chain.

An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. The application of force is the location at which force is applied, and the direction in which the force is applied is known as the direction of the force.

Given that:

Mass of the  hunk of anorthosite moon rock : m = 500.0 kg.

Acceleration of the hunk: a = 4.0 m/s².

Acceleration due to gravity in moon = 1.625 m/s².

So, required force = 500.0(4.0 +1.625) n = 2812.5 N.

The force of 2812.5 N is being exerted by the chain.

We want to convert the speed of the bus from kilometers per hour to meters per second.

To do this, multiply the speed in km/hr by 1,000 and divide by 3,600.

The formula to do this is: 1 km/hr = 1,000/3,600 m/s

Therefore, we have that 45 km/hr is:

45 x 1000/ 3,600 ➡️ 12.5 m/s = 1.25 x 10 to the 1st power m/s

Fuller pillows that keep her neck straight. The correct option is A.

Thus, Broader pillows that properly support her neck and head would be a better choice. Better sleeping posture and a lower incidence of neck and back pain can both be encouraged by pillows that keep the neck and spine in their natural alignment.

Flat pillows could not offer enough support, which could result in poor alignment and long-term discomfort or suffering.

Stacking pillows in Option B may provide some elevation, but it might not necessarily provide the essential neck and spine support. Option C (without using pillows) can fail to give the head and neck the necessary support and cushioning.

The statement which fairly compares segment 2 and segment 3 is These represent equal periods of time, but the force during segment 2 is different than the force during segment 3.

Since segment 2 starts at t = 60 s and ends at t = 150 s, the time interval is Δt = 150 - 60 = 90 s.

Also, segment 3 starts at t = 150 s and ends at t = 240 s, the time interval is Δt = 240 - 150 = 90 s.

So, their time periods are the equal.

We notice that segment 2 is less steep than segment 3 this implies that the acceleration in each segment is different, since the acceleration is the slope of the graph.

Since force is determined by acceleration, this implies that the force on segment 2 is different form the force acting in segment 3.

So, we have equal time periods but different forces.

Answer:

The fundamental function of snowshoes is to offer float, allowing you to avoid sinking into snow. Hikers who do not have snowshoes may find themselves knee- or waist-deep in unconsolidated snow if they attempt to traverse it without snowshoes, a practice known as post-holing.

Explanation:

Answer:

Explanation:

I live in a cold country and I own snow shoes. I have to confess I've never thought about this question before.

If the snow is fresh, it is also very loosely packed. If you wear ordinary shoes, the first thing that will happen is that you will sink. How far depends on how deep the snow is. I can see you up to your waist in snow, if the snowfall is heavy enough.

So to prevent that, my snowshoes are 3 feet long and about 1 foot wide, Except for a small hole near the middle, the entire area is covered. I weigh about 140 pounds.

A very small calculation should tell you that if I wear house shoes (mine are 8" long by about 3 inches wide). The pressure is going to be 140 pounds / (2/3 * 1/4) = 140 // 2/12 = 140 / 1/6 = 140 *  6 = 840 pounds / square foot. Trust me, that is a lot of pressure.

What do the snowshoes accomplish?

140 / (3*1) = 46.7 pounds per square foot. You might sink a little, but you are not going down as far as you would with street clothes shoes.

The units are not the normal units you would use, but the ratio is going to be roughly the same. 840 / 46.

All of this is very approximate. That's what physics is all about. Approximations lead you to understanding.

This question involves the concepts of centripetal force and centripetal acceleration.

a) The centripetal acceleration for the piece of gum stuck to the outside edge of the record will be "6.67 m/s²".

b) The gum will have to overcome "0.033 N" centripetal force to remain stuck to the vinyl.

a)

The centripetal acceleration of the gum can be found using the following formula:

[tex]a_c=\frac{v^2}{r}[/tex]

where,

[tex]a_c[/tex] = centripetal acceleration = ?

v = linear speed of record = 1 m/s

r = radius of the record = [tex]\frac{diameter}{2}=\frac{0.3\ m}{2}=0.15\ m[/tex]

Therefore,

[tex]a_c=\frac{(1\ m/s)^2}{0.15\ m}\\\\a_c = 6.67\ m/s^2[/tex]

b)

Now, the centripetal force can be given as follows:

[tex]F_c=ma_c\\F_c=(0.005\ kg)(6.67\ m/s^2)\\F_c=0.033\ N[/tex]

Considering the Law of Universal Gravitation, the mass of the second object is 78090.19 kg.

The Law of Universal Gravitation is a law that states that bodies, by the simple fact of having mass, experience a force of attraction towards other bodies with mass, called gravitational force.

This law establishes that every particle attracts any other particle with a force directly proportional to the product of the masses of both and inversely proportional to the square of the distance that separates them:

[tex]F=G\frac{m1m2}{r^{2} }[/tex]

where m1 and m2 are their masses; r the distance between them and G a universal constant that is called the constant of gravitation.

In this case, you know:

Replacing:

[tex]0.128 N=6.67x10^{-11}\frac{Nm^{2} }{kg^{2} } \frac{1300 kg m2}{(0.23 m)^{2} }[/tex]

Solving:

[tex]0.128 N=1.639x10^{-6}\frac{N}{kg }x m2[/tex]

m2=0.128 N ÷ 1.639×10⁻⁶ [tex]\frac{N}{kg}[/tex]

m2=78090.19 kg

In summary, the mass of the second object is 78090.19 kg.
