SUMMARY
The discussion focuses on calculating the velocity of the first car after a collision using the law of conservation of linear momentum. Given a 480 kg car moving at 14.4 m/s collides with a 570 kg car moving at 13.4 m/s, the final velocity of the first car is determined to be 8.94 m/s. The equation used is m1u1 + m2u2 = m1v1 + m2v2, where m1 and m2 are the masses of the cars, and u1 and u2 are their initial velocities.
