1. Chapter 5 Momentum Ewen et al. 2005) Objective: Apply the law of conservation of momentum to both elastic and inelastic collisions of two objects. Apply the law of conservation of momentum to both elastic and inelastic collisions of two objects.

2.  Whenever two objects collide in the absence of external forces, the total momentum of the objects before the collision equals to the momentum after the collision.

3.  When two objects collide and return to their original shape without being permanently deformed.

4.  When two objects collide and couple together.

5.  Elastic Collision  Inelastic Collision

6.  One ball of mass 0.600 kg traveling 9.00 m/s to the tight collides with a second ball of mass 0.300 kg traveling to the left. After the collision, the heavier ball is traveling 2.33 m/s to the left. What is the velocity of the lighter ball after the collision?

7.  A 1.75 E4 kg railroad car traveling 8.00 m/s to the east collides and couples with a stopped 2.25 E4 kg railroad car. What is the velocity of the joined railroad cars after the collision?
