Anyone good with calculus? Please help.

First take a time derivative of a function describing motion,

.

Finding the maxima of the function is obtained by determining where the critical points are. You can find the critical points by equating the derivative with 0 and solving for t,

.

So at 2 seconds the ball peaks in height.

To find out the height feed 2 to the function h.

.

So at 2 seconds the ball reaches maximum height of 5 meters.

Hope this helps :)
