This problem is an extension of the two momentum principle videos from week 5. All four will be posted here, but only the videos labelled Part A and Part B deal with inelastic and elastic collisions.

Part 1: Momentum principle from week 5.

Part A: Inelastic & Elastic evaluation for Part 1

Part 2: Momentum principle from week 5.

Part B: Inelastic & Elastic evaluation for Part 2
