11. Momentum & Impulse Elastic Collisions
2PRACTICE PROBLEM
Two cars collide with each other. Car A has a mass of 1000 kg and is moving towards car B with a velocity of 20 m/s. Car B has a mass of 800 kg and is at rest. What is the velocity of each car immediately after they collide?
We assume this is a one-dimensional collision that obeys the conservation laws of momentum and
mechanical energy.
