Two blocks are sliding along a frictionless track. Block A (mass 3.25 kg) is moving to the right at 1.60 m/s. Block B (mass 3.90 kg) is moving to the left at 1.92 m/s. Suppose the system to be both Block A and Block B.
1. What is the total momentum of the system after the collision? left or right?
2. What is the total momentum of the system before the collision? left or right?
3. The two blocks stick together and move off together. What is the direction and magnitude of the velocity of the blocks after the collision? left or right?
