You throw a football straight up. Air resistance can be neglected. (a) When the football is 4.00 m above where it left your hand, it is moving upward at 0.500 m/s. What was the speed of the football when it left your hand

The speed of the football when it lift your hand is 8.86 m/s.

Explanation:

Given that,

Final speed of the football, v = 0.5 m/s

Height above the ground, s = 4 m

We need to find the speed of the football when it left your hand. The ball will move under the action of gravity. Using third equation of motion as:

So, the speed of the football when it lift your hand is 8.86 m/s. Hence, this is the required solution.
