The physics
Momentum is 'quantity of motion': mass times velocity. It measures how hard something is to stop. A slow lorry and a fast bicycle can carry similar momentum — and require a similar impulse to bring to rest.
Momentum of a 0.057 kg tennis ball served at 200 km/h
Answer: momentum = 3.17 kg·m/s.
What we know
- Mass: 0.057 kg
- Velocity: 200 km/h = 55.55555556 m/s (converted to the unit the formula takes)
Step by step
- Given
- m = 0.057 kg, v = 55.55555556 m/s
- Formula
- p = m × v
- Substitute
- p = 0.057 × 55.55555556
- Result
- p = 3.17 kg·m/s
