Question

A table tennis ball with a mass of 0. 003 kg and a soccer ball with a mass of 0. 43 kg are both set in motion at 16 m/s. Calculate and compare the momenta of both balls.

Answer 1

0.048 kgm/s, 6.88 kgm/s

Step-by-step explanation:

m = 0.003 kg, M = 0.43 kg, v = 16 m/s

The momentum of a table tennis ball = mv = 0.003 * 16 = 0.048 kgm/s

The momentum of a soccer ball = Mv = 0.43 * 16 = 6.88 kgm/s

The two balls have same speed, but different masses. A table tennis ball has smaller mass, so the momentum is smaller too.
