Answer:

V = U + at

Explanation:

<u>Given the following data;</u>

Initial velocity = 0 (since the stone is starting from rest).

Final velocity = 32 m/s

Acceleration = g = 10 m/s²

Time = 3.2 seconds

To show that the speed of the stone when it hits the ground is 32 m/s, we would use the first equation of motion;

V = U + at

Where;

  • V is the final velocity.
  • U is the initial velocity.
  • a is the acceleration.
  • t is the time measured in seconds.

Substituting into the formula, we have;

32 = 0 + 10*3.2

32 = 0 + 32

32 = 32

<em>Proven: 32 m/s = 32 m/s</em>

What is the average kinetic energy of protons at the center of a star where the temperature is 190e7K?
valkas [14]
I'm pretty sure that you put incorrect temperature number, since the number of temperature that you currently given does not make any sense.

Insert your correct temperature in this equation :
Ek = (3/2)kT

Hope this helped you out

What is the kinetic energy of a 478 kg object that is moving with the speed of 15 m/s
Tpy6a [65]
Kinetic energy = (1/2)*mass*velocity^2
KE = (1/2)mv^2
KE = (1/2)(478)(15)^2
KE = 53775J
