A ball is launched directly in the air at a speed of 60 feet per second from a platform located 20 feet in the air. The motion of the ball can be modeled using the function f(--16t+60t+20, where tis the time in seconds and fAt) is the height of the ball. After approximately how much time, in scconds, will the ball hit the ground?
