Question

A ball is launched from a 70.56-foot tall platform. The equation for

the ball's height h at time t seconds after launch is h (t) = -16t² +
70.56, where h is in feet. What is the maximum height the ball
achieves before landing?

Answer 1

In this case the equation is already in vertex form. The vertex of the parabola is the maximum point and the value of h(t) at that point is the maximum height.

Since the equation is h(t) = -16t² + 70.56, the maximum height is 70.56 feet.
