11. Momentum & Impulse Completely Inelastic Collisions
3PRACTICE PROBLEM
Science students decide to perform an experiment on a horizontal and frictionless rink. John (mass = 70.0 kg) stands still while James (mass = 53.0 kg) skates in a straight line and collides with John with a velocity of 12.5 m/s. After the collision, James is deflected at 46.8° from his original direction and has a speed of 6.50 m/s. Determine the change in kinetic energy of the system following the collision.
