Question

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.
