In the lab, a 1.0 kg cart traveling in the +x direction with a speed of 0.5 m/s collides with a 2.0 kg cart that is moving in the +x direction at 0.2 m/s. If the velocity of the more massive cart after the collision is 0.3 m/s, what is the change in internal energy of the system of the two carts?

A car of mass 500 kg and a truck of mass 1200 kg are moving directly toward each other at the same speed of 20 m/s. Define the +x direction to the direction of the car.

  1. What is the velocity of the center of mass of the system, defined to be the car and truck?
  2. At the moment when the vehicles are 100 m apart, what is the location of the center of mass of the system? Treat the vehicles as point particles.
