Determine the speed of the two wagons immediately after they stick together?

Posted on January 4, 2012 by admin

The wagon and mass continue moving until reaching another frictionless wagon of mass 15.0 kg at point B. This wagon is attached to a spring of negligible mass which has a spring constant of 250 N/m. The other end of the spring is fixed to the wall. Upon impact, the two wagons stick together ad compress the spring.

This problem is missing some information. Where does the mass come into play? The first part of your "question" says that the wagon and mass "continues" moving, implying that something happened before it.

Can you edit the question please?

    mvi = 2mvo

    vo= 1/2 vi

    With that ou can determine the length of the spring:

    1/2 (2m) vo^2 = 1/2 k x^2
