A 0.650 kg basketball is dropped out of a window that is 6.46 m above the ground. The ball is caught by a person whose hands are 1.32 m above the ground. How much work is done on the ball by its weight?
1.56 seconds
The work done is the reduction in the potential energy of the ball at 5.50 metres to its PE at 2.05 m above ground level. This is 20.6 Newtons (to 1 dp).
Still accelerating til it hits earth. ====================================== The height from which she dropped the ball is irrelevant. In any case, the ball was most likely moving at the greatest speed just as it hit the ground. The answer to the question is: zero.

Assuming both were dropped from the same height above ground, in a vacuum both would hit the ground at the same time. In a significant atmosphere (e.g. average ground-level on Earch) the bowling ball would hit the ground first.

Who has dropped the ball? The referee?! If the referee drops the ball after he interrupted the game the ball is in play when the ball touches the ground. It isn't allowed to score a goal directly from a dropped ball, two players have to touch the ball before the goal counts.
A ground ball is when a player picks the ball up from the ground. The ball is often dropped and ground ball pickups are a vital skill to have. A ball thrown and intercepted by the opposing team is also considered a ground ball for the person intercepting the pass.
If dropped from the same height, they will hit the ground at the same time.
