Question

A 45 kg ice skater at rest caught a 0.25kg ball, If the ice skater moved at 0.15 m/s after catching the ball, find the speed of the ball before he caught it.

Answer 1

27 m/s

Step-by-step explanation:

Momentum is conserved.

Initial momentum = final momentum

(0.25 kg) v = (45 kg + 0.25 kg) (0.15 m/s)

v ≈ 27 m/s
