To study how high a ball bounces, students drop the ball from various heights. The function h(t) = −16t2 + h0 gives the height (in feet) of the ball at time t measured in seconds since the ball was dropped from a height of h0. If the ball is dropped from a height of 22 feet, find the elapsed time until the ball hits the floor. Round to the nearest tenth.
The ball will hit the ground after approximatelyseconds.
