Compression of a Spring

  1. Jan 29, 2012 #1
    1. The problem statement, all variables and given/known data
    A 1 kg cart is at the top of a frictionless ramp as shown. It rolls down and makes an elastic collision with a stationary 3 kg cart at the bottom. The spring constant is 400 N/m. What is the maximum compression of the spring? How far up the ramp will the first cart travel after the collision?

    3. The attempt at a solution
    I got part a, but I don't know how to do part b.

    Thanks!

    No figure.

    Not enough detail given -- especially without the figure !

    How did you find the maximum compression of the spring? --- in detail.
