An object is launched straight into the air. The projectile motion of the object can be modeled using h(t) = 96t – 16t2, where t is the time since launch and h(t) is the height in feet of the projectile after time t in seconds. When will the object be 144 feet in the air? after 1.5 secondsafter 3.0 secondsafter 6.0 seconds. When will the object hit the ground? after 2.5 secondsafter 5.0 secondsafter 6.0 seconds
