The following shows the before and after of a collision. For each case, determine whether the collision is elastic, inelastic, or perfectly inelastic, and then rank the collisions for the largest change in momenta for the object initially on the left.

Case 1:

A 1kg box moving to the right vi=3 m/s and vf=0 m/s

A 3kg box moving to the left vi=-1m/2.

Case 2:

A 3kg box moving to the right vi=3 m/s and vf=-1 m/s.

A 1kg box moving to the left vi=-1m/s.

Case 3:

A 3kg box moving to the right vi=3 m/s and vf=1 m/s.

A 1kg box moving to the left vi=-1m/s.

You are trying to determine the velocity of an asteriod using an elastic collision. You fire a 1 kg projectile to the right moving with speed 1 m/s toward on 100 kg mass that is moving left with some unknown speed. After an elastic collision, we measure that the launced projectile bounces back toward you with a speed of 40.58 m/s. Find the initial speed of the larger 100 kg mass

Suppose the two cars had rubber bumpers in the front and back – similar to the bumper cars children (of all ages!) ride at amusement parks. Also, suppose that the cars are sturdy enough that the metal they are made of does not bend during the collision. In this case, the cars would undergo a perfectly elastic collision. Assume just like in the first collision question that the SUV (initially moving to the right) collides into the stationary smart car....
