The surface of the pool table is ℎ=0.790 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 at a distance of =5.05 m from the table's edge, calculate the speed of his break shot 0. Assume friction is negligible.

At what speed 1 did his pool ball hit the ground?

The calculated velocity is 3.88 m/s

Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path. In other words, velocity is a vector, whereas speed is a scalar value. The parameters of speed are time divided by distance. The most often used unit of speed in daily life is the kilometer per hour (km/h), or miles per hour in the US and the UK. The SI's unit of speed is the meter per second (m/s) (mph).

h = 0.5g*t² = 0.77 4.9t²

= 0.77\st²

= 0.1571

t = 0.396 seconds or fall.

Dx = Xo*t, or 5.15 meters.

Xo * 0.396 = 5.15

Break speed is X= 13 m/s.

V² = V² + 2g*h.

V² = 0 + 19.6*0.77

= 15.09

V = 3.88 m/s
