Question
What is the rate of change of momentum of the following box.
- m(v - u)
- m(v + u)
Hint:
The change in momentum of an object is its mass times the change in its velocity
The correct answer is:
The change in momentum of an object is its mass times the change in its velocity
So Rate of change momentum =
