A projectile is launched from ground level with an initial velocity of v0 feet per second. Neglecting launch is given by s=-16t^2+v0^t. Find the time(s) that the projectile will (a) reach a height of 272 ft and (b) return to the ground when v0 is 32 feet per second.

neglecting launch?

dumbcow · Answer

you plug in 32 for v_0
then set s = 272 and s=0  and solve for "t" using quadratic formula
