# 1) A ball is projected upward from the top of a 144 feet building at a velocity of 64 feet per second.

1) A ball is projected upward from the top of a 144 feet building at a velocity of 64 feet per second. It's 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 seconds.
