Two carts, one of mass 2kg and another of mass 4kg are driving towards each other with a speed 3m/s. Assume the mass 2kg is moving to the right.

Question

Which cart has the most momentum?
What is the total momentum of the system?
After the collision, what is the total momentum of the system?
Suppose that after the collision, the cart of mass 2kg has a new velocity of -5m/s. What is the new velocity of the cart of mass 4kg.

Answer 1

I will be happy to critique your work. I assume you do not have a question on this problem, it is straightforward conservation of momentum
