Elastic collision: spring compression during elastic collision + maximum compression of the spring.

Subscribe to Zak's Lab https://www.youtube.com/channel/UCg31-N4KmgDBaa7YqN7UxUg/ Compressing a spring during a collision: In this spring compression momentum problem, we calculate the maximum compression of the spring during an elastic collision. Unlike most perfectly elastic spring problems, we aren't interested in the final velocity after the collision, and that problem is solved in another video here: https://www.youtube.com/watch?v=KgMtfgjkBwM In this elastic collision spring compression problem, we tackle the problem of finding spring energy during the elastic collision by using conservation of momentum to find the velocity of the combined masses at the moment of maximum compression of the spring (when the two speeds are equal), then we use the kinetic energy formula to find the spring energy stored during the elastic collision (the "missing" energy here) and we use the spring energy formula to find the maximum spring compression during elastic collision.
