A ball rolls horizontally off the edge of a tabletop that is 1.60 m high. It strikes the floor at a point 1.58 m horizontally away from the table edge. (Neglect air resistance.)How long was the ball in the air? What was its speed at the instant it left the table?

The time in the air depends on height.

h= 1/2 g t^2 solve for t.

speed= horizontal distance/t
