A projectile is launched from ground level with an initial velocity of v 0 feet per second.
Question:
A projectile is launched from ground level with an initial velocity of v0 feet per second. Neglecting air resistance, its height in feet t seconds after launch is given by
s = -16t2 + v0t.
Find the time(s) that the projectile will (a) reach a height of 80 ft and (b) return to the ground for the given value of v0. Round answers to the nearest hundredth if necessary.
v0 = 96
