Problem 8.12: Analyze several two-d collisions

Please wait for the animation to completely load.

Several two-dimensional collisions between two balls (the green ball is ball 1 and the blue ball is ball 2) are shown (position is given in meters and time is given in seconds). Also shown is a protractor, which you can drag around (by the little circles on its legs) to measure angles. Restart.

For each animation:

  1. Determine the initial momentum of each ball
  2. Determine the final momentum of each ball.
  3. Calculate and compare the initial momentum to the final momentum for the two-ball system.
