Question

A ball is rolling down a hill. At the bottom of the hill, its traveling at 15 m/s. The ball has a mass of 10 kg. What is the kinetic energy of the ball at the bottom of the hill?

a) 150 J
b) 2250 J
c) 1125 J
d) 300 J

Answer 1

C. 1125 J Yeeeeeeeeee

Answer 2

C)1125 J because the formula for kinetic energy is 1/2 multiplied by mass multiplied by volume to the second power. So 1/2 multiplied by 10 multiplied by 15 to the second power is 1125 if that makes since.
