A ball with a horizontal speed of 1.25 {\rm m/s} rolls off a bench 1.00 {\rm m} above the floor.
How long will it take the ball to hit the floor?
How far from a point on the floor directly below the edge of the bench will the ball land?

Exactly as long as it would take anything else to fall of the bench to the floor.
v = sqrt (2 g h) = sqrt (2*9.8*1) = 4.43 m/s when it hits the floor. Average vertical speed is half that
2.21 m/s average falling speed
1 = 2.21 * time
time = .452 seconds to fall

distance = speed * time
= 1.25 * .452 = .565 meters
