A ball is thrown vertically upward with an initial velocity of 96 feet per second. The distances (in feet) of the ball from the ground after t seconds is
s = 96t - 16t²
(a) At what time t will the ball strike the ground?
(b) For what time t is the ball more than 44 feet above the ground?
s=96t-16t²
44 ft
