Problem 8.3: Determine Δp for two collisions

Please wait for the animation to completely load.

Two carts collide with a wall as shown in the animation (position is given in meters and time is given in seconds). Assume the two carts are identical. Restart.

  1. Is kinetic energy constant for either collision?
  2. Which cart, top or bottom, undergoes the greater change in kinetic energy due to colliding with the wall?
  3. Is this the same cart that undergoes the greater change in momentum?
  4. Explain how carts can change their momentum but not their kinetic energy.
