4. If a projectile is shot vertically upward from the ground with an initial velocity of 100 feet per second, neglecting air resistance, its height s (in feet) above the ground t seconds after projection can be modeled by s= -16r +1001. SLO 13 a) How long will it take for the projectile to return to the ground? b) When will it reach maximum height? c) What is the maximum height?
