the top of the pool table is 0.710m from the floor. the placement of the tape is such at 0m aligns to the edge of the table. the winner of the competition wants to know if he has broken the world record for the break shot of 32mph ( about 14.3m/s) the ball landed a distance of 3.65m from the table edge.
1. calculate his break shot speed
2. at what speed did his pool ball hit the ground?
