The top of the pool table is 0.770 m from the floor. The placement of the tape is such that 0 m 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 (about 14.3 m/s). The ball landed a distance 5.15 m from the table edge, calculate his break shot speed.

At what speed did his pool ball hit the ground?

4.9t^2 = 0.77

t^2 = 0.1571

t = 0.396 s. = Fall time.

Dx = Xo * t = 5.15 m.

Xo * 0.396 = 5.15

Xo = 13 m/s = Break speed.

b. V^2 = Vo^2 + 2g*h

V^2 = 0 + 19.6*0.77 = 15.09

V = 3.88 m/s
