What is the formula for the height of a rocket fired upward?

Back

h = -16t² + 1600t, where h is the height in feet and t is the time in seconds.

Front

At what time does a rocket reach its maximum height if its height is given by h = -16t² + 1600t?

Back

The rocket reaches its maximum height at 50 seconds.
