Two golf balls of equal size and mass are released simultaneously from the roof of a building. One of the balls has a smooth surface while the other one has grooves on it. They then hit on a hard and horizontal plane on the floor. Assume that the golf balls are not worn after colliding with the hard plane and the effect of air resistance is considered, describe and explain which ball can reach a greater height after rebound.

Answer 1

it would have to be a very tall building to notice these effects.

Answer 2

So does it mean that the ball with grooves can reach a higher velocity and rebound to a greater height?
