Car A is traveling at 25 m/s. It experiences an inelastic collision after hitting a brick wall. Car B is traveling at 25 m/s. It experiences an elastic collision with a return
velocity of 6 m/s.
Compare the elastic collision of Car A to the inelastic collision of Car B. Both cars
have the same mass of 1500 kg. What is the difference (subtract the two) of
momentum between Car A and Car B.
