Question

Which has more momentum: a 30 kg bicycle moving at 10 m/s or a 300 kg car at rest?

A bicycle
B car
c they have the same momentum

Answer 1

Momentum = mass × velocity

Case I

Momentum of bicycle = 30 × 10 = 300 kgms¯¹

Case II

Momentum of car = 300 × 0 = 0 kgms¯¹

Therefore, 300 > 0 so momentum of bicycle is more. Hence, option A is correct.
