If a projectile is fired straight upward from the ground with an inital speed of 96 feet per second, then its height (h) in feet after t seconds is given by the equation
h(t)=16t^2+96t
Find the maximum height of the projectile.

Henry,
Tr = (VVo)/g.
Tr = (0960 / 32 = 3 s. = Rise time.
h(t) = 16*3^3 + 96*3 = 144 Ft.
