For each situation, you need to determine if the object has KE or GPE or both. Then find their values.

A 2-kg bowling ball rolls at a speed of 10 m/s on the ground.

 

Circle one: KE / GPE / both

 

Show your work for finding the values of each type of energy the object has:

 

MY ANSWER

The ball has KE since it is rolling.

1/2mv^2=1/2*2kg*10m/s=10j

Close....   It does NOT have GPE since it is not elevated above the ground

 

It DOES have Kinetic Enegy because it is rolling  1/2  m v^2  =   1/2  2 kg  (10 m/s)^2 = 100 j
