Question
Identify what is wrong in this statement.
Rate of change of momentum = 
- It should be initial momentum minus final momentum.
- Acceleration should be multiplied.
- a needs to be replaced with t.
- There will be no denominator.
Hint:
Rate of change of momentum= m(v-u)/t
The correct answer is: a needs to be replaced with t.
- Change in momentum= m(v-u).
- Rate of change of momentum= m(v-u)/t.
- a needs to be replaced with t.
