Car A has a mass of 1000 kg and is moving at 30 km/h. Car B has a mass of 2000 kg and is moving at 30 km/h.?

Question

The momentum of car A is ________________.

A. equal to that of car B

B. half that of car B

C. twice that of car B

D. 4 times that of car B

Answer 1

B. half that of car B

momentum is based on the equation p=mv (momentum equals mass times velocity). We can simply say that because the mass of car A is half that of car B and they have identical velocities, the momentum of car A is half that of car B.

Answer 2

momentum = mass x velocity

Answer 3

B
