Puddy hitting a mass attached to spring

  1. May 22, 2009 #1
    1. The problem statement, all variables and given/known data

    A block of mass M rests on a frictionless horizontal surface and is attached to a wall by a spring of spring constant k. A blob of putty of mass m and horizontal speed v collides with and sticks to the block. Find the maximum compression of the spring.

    can anyone help?

    Too funny. I saw the title of this thread, and thought a cat was the projectile! :rofl:

    Welcome to the PF. Use total energy to solve the problem. TE = KE + PE.
