Question

Car A

Mass: 1,500 kg

Velocity: 10 m/s

Car B

Mass: 1,500 kg

Velocity: 25 m/s

Car C

Mass: 1,000 kg

Velocity: 10 m/s

Which order shows decreasing momentum?

A, B, C
B, A, C
C, B, A

Answer 1

Momentum = mass × velocity.

- Car A: 1500 kg × 10 m/s = 15,000 kg·m/s
- Car B: 1500 kg × 25 m/s = 37,500 kg·m/s
- Car C: 1000 kg × 10 m/s = 10,000 kg·m/s

Decreasing momentum: B, A, C.
