The top of the pool table is 3.05 ft from the floor. The placement of the tape is such that 0 feet aligns to the edge of the table (as shown). The winner of the competition wants to know if he has broken the world record for the break shot of 32 mph. His ball landed a distance 12.25 ft from the table edge. Calculate his break shot speed in mph and at what speed did his ball hit the ground (in mph)

find the flight time
... 0 = -16 t^2 + 3.05
break shot speed
... 12.25 ft / flight time
(impact speed)^2 =
... (break shot speed)^2 + (t * 32 ft/s^2)^2
... 0 = -16 t^2 + 3.05
break shot speed
... 12.25 ft / flight time
(impact speed)^2 =
... (break shot speed)^2 + (t * 32 ft/s^2)^2
