, b) 
Explanation:
a) The maximum height is obtained with the help of the First and Second Derivative Tests:
First Derivative
Second Derivative
(absolute maximum)
The maximum height reached by the ball is:
b) The time required by the ball to hit the ground is:
Just one root offers a solution that is physically reasonable:
The velocity of the ball when it hits the ground is:
