Problem
Suppose that you throw a ball straight up at 10 m/s and release it at 2 m above the ground.
(a) What maximum height above the ground does the ball reach?
(b) How long after you release it does the ball hit the ground?
(c) What is the magnitude of its velocity just before it hits the ground?
