If a ball is shot from the ground straight up into the air with an initial velocity of 64 ft/sec its height in feet in feet after t seconds is given by h(t)=64t-16t^2

When will the ball hit the ground, and what is the maximum height the ball will reach?

A ball is projected upward from the top of a 144 feet building at a velocity of 64 feet per second. Itâs path is described by the function h(t)= -16t^2+64t+144, where t is the time after the ball is projected and (h)t is the height of the ball at any time t seconds.
