(1.) A 0.5 kg basketball rolls off the roof of a building. At a moment when it is 3 m above the ground, it has a speed of 2.5 m/s. What is the total mechanical energy of the basketball ?

(2.) In the previous problem, how much kinetic energy does the football possess just after the throw? Assume that the football started from rest.

Answer:

The answer is C.

Step-by-step explanation:
