Provided that:
- Initial velocity = 20 m/s
- Final velocity = 36 m/s
- Mass = 3.5 kg
To calculate:
- Change in momentum
Solution:
- Change in momentum = 56 kg m/s
Required solution:
~ Firstly let us calculate the initial momentum in given case!
→ p = mu
→ p = 3.5 × 20
→ p = 70 kg m/s
~ Now let us calculate the final momentum in given case!
→ p′ = mv
→ p′ = 3.5 × 36
→ p′ = 126 kg m/s
~ Now let us calculate change in momentum!
→ ∆p = p′ - p
→ ∆p = 126 - 70
→ ∆p = 56 kg m/s
- Therefore, 56 kg m/s is the change in momentum!
