Question: A ball rolls off a table and lands on the floor. The horizontal distance between the position at which the ball lands and the edge

A ball rolls off a table and lands on the floor. The horizontal distance between the position at which the ball lands and the edge of the table is $0.50 \mathrm{~m}$, and the tabletop is $0.80 \mathrm{~m}$ above the floor.

(a) How long does it take the ball to reach the floor?

$(b)$ What is the ball's speed when it leaves the table?
