Question

 

Cart A has a speed of 1.5 m/s in the +x direction and Cart B is at rest when they collide. After the collision, Cart A rebounds in the –x direction with a speed of 0.75 m/s, and Cart B travels in the +x direction with a speed of 0.75 m/s. The mass of Cart A is 0.50 kg, and the mass of Cart B is 1.5 kg.

  1. Define Cart A to be the system. What is the change in momentum of the system due to the collision?
  2. Define Cart B to be the system. What is the change in momentum of the system due to the collision?
  3. Define Cart A and Cart B, together, to be the system. What is the change in momentum of the system due to the collision?
