Question

A 50-g ball rolls across a table at 2 m/s. A 100-g ball rolls across the same table at 1 m/s. Which ball has more momentum?

a. 50-g Ball
b. 100-g ball
c. They have the same momentum

Answer 1

Momentum = Mass * Velocity.

50 g ball: 50 g * 2 m/s = 100 gm/s

100 g ball: 100 g * 1 m/s = 100 gm/s

They have same momentum.

c. They have the same momentum
