Homework Help: Kinetic Energy of a wood on a spring?

  1. Mar 10, 2009 #1
    1. The problem statement, all variables and given/known data

    When a piece of wood is pressed against a spring and compresses the spring by 4.00cm , the wood gains a maximum kinetic energy K when it is released.

    How much kinetic energy (in terms of K) would the piece of wood gain if the spring were compressed 20.0 cm instead? K_2 = ___K

    2. Relevant equations


    3. The attempt at a solution

    How do I begin this problem?
