Two cars collide in an inelastic collision where they become entangled. An inelastic collision is where objects stick together after impact. The total momentum before the collision equals the total momentum after. A 1850 kg sedan is stopped when hit from behind by a 975 kg compact car going 22.0 m/s north. The problem is to calculate the velocity of the entangled mass after the collision.

1. COLLISIONS

2. Inelastic CollisionsA collision in which two objects stick together after colliding is called inelastic collision.

3. The total momentum of the two cars before the collision (a) is the same as the total momentum of the two cars after the inelastic collision (b).

4. Problem:A 1850 kg luxury sedan stopped at a traffic light is struck from the rear by a compact car with a mass of 975 kg. The two cars become entangled as a result of the collision. If the compact car was moving at a velocity of 22.0 m/s to the north before the collision, what is the velocity of the entangled mass after the collision?
