A baby stroller is a rest on top of a hill which is 10 m high. The stroller and baby have a mass of 20 kg. What is the potential

Anettt [7]

The potential energy is defined as the energy is contained in the body due to the height over the surface of the earth and it is calculated from the equation

$PE=mgh$

<em>where:</em>

PE: the potential energy in Joules.
m: the mass of the body in kg.
g: the acceleration due to the gravity in m/ $s^2$
h: the height of the body over the earth in meters.

<em>in our problem:</em>

$PE=20*9.8*10=1960 J$

A ball player catches a ball 3.24 s after throwing it vertically upward.With what speed did he throw it?

Firdavs [7]

Doesn't seem like we know much here, but we can answer it. Let's talk about what we know. We know it takes 3.24 s for the ball to go up and drop back down again. We know that gravity is the only force acting after the ball leaves the hand, so a = 9.8 m/s^2 (we'll say it's negative in our equations because down being negative is intuitive). We also know that it stops moving for a brief moment at the top of the arc, where v = 0 m/s. Because gravity is the only force, and it slows it down on the way up at the same rate it speeds it up on the way down and the distance covered in upward and downward motion is the same, we can confidently say that it will reach the top of its arc (where v = 0 and it turns around) in half the total time it is in the air, so it takes 1.62 s to reach the peak. Now we can use a kinematics equation, let's use vf = vi + a*t, where vf is final velocity and is 0, vi is initial velocity and is some unknown v we need to solve for, a is acceleration and is -9.8 m/s^2 and t is time and since this is just to the top of the arc, we'll use half the time so 1.62 s. We can solve for vi and plug stuff in like so: v = -a*t = -(-9.8m/s^2)*(1.62s) = 15.876 m/s.

1. An object is moving at 4.66 m/s when it accelerates at 5.66 m/s2 for a period of 2.35 s. The distance it moves in this time i

lesya [120]

Answer:

1. Distance, S = 26.58 meters

2. Acceleration of gravity, g = 58.60 m/s²

Explanation:

1. Given the following data;

Initial velocity = 4.66 m/s

Acceleration = 5.66 m/s²

Time = 2.35 seconds

To find the distance travelled by the object, we would use the second equation of motion;

S = ut + ½at²

Where;

S represents the displacement or height measured in meters.

u represents the initial velocity measured in meters per seconds.

t represents the time measured in seconds.

a represents acceleration measured in meters per seconds square.

Substituting into the equation, we have;

S = 4.66*2.35 + ½*5.66*2.35²

S = 10.951 + (2.83 * 5.5225)

S = 10.951 + 15.629

S = 26.58 meters

2. Given the following data;

Displacement (height) = 1.55 m

Time, t = 0.23 seconds

To find the acceleration of gravity, we would use the following formula;

Height = ½gt²

Substituting into the formula, we have;

1.55 = ½ * g * 0.23²

1.55 = ½ * g * 0.0529

1.55 = 0.02645g

Acceleration of gravity, g = 1.55/0.02645

Acceleration of gravity, g = 58.60 m/s²
