1. Answer the following questions:

a.  What is the formula for momentum? Explain what each term means.

b. In your own words, what is momentum?

2. True or False:

a. Momentum is conserved in elastic collisions, but not in inelastic collisions.

True
False

b.  Kinetic energy is conserved in inelastic collisions, but not in elastic collisions.

True
False

c.  In a car accident, the collision is considered perfectly elastic.

True                                                                                                                                                                                    False

d. Collision between billiards balls is an example of an elastic collision.

True                                                                                                                                                                                    False

e. The reason why energy is not conserved in inelastic collisions is because of human error.

True                                                                                                                                                                                    False

3. A mass of .6 kg moving with a velocity of 2.4 m/s in the positive direction experiences a totally inelastic collision with a mass of 1.1 kg. What is the final velocity of the masses?

4. A mass of .43 kg moving with a velocity of 1.5 m/s in the positive direction experiences an elastic collision with another mass of .22 kg moving with a velocity of 3.4 m/s in the negative direction. What will the velocities of the two masses be after the collision? Remember that in elastic collisions, both kinetic energy and momentum are conserved.
