Pool players often pride themselves on their ability to impart a large speed to a pool ball. In the sport of billiards, event organizers often remove one of the rails on a pool table to allow players to measure the speed of their break shots (the opening shot of a game in which the player strikes a ball with his pool cue). With the rail removed, a ball can fly off the table, as shown in the figure. Vo h d The surface of the pool table is h = 0.850 m from the floor. The winner of the competition wants to know if he has broken the world speed record for the break shot of 32 mph (about 14.3 m/s). If the winner's ball landed a distance of d = 4.05 m from the table's edge, calculate the speed of his break shot Vo. Assume friction is negligible. m/s Vo = At what speed ₁ did his pool ball hit the ground? m/s 01 =
