No one has figured this out! Problem I'm stuck

  1. Jan 6, 2009 #1
    a block of mass 2.0 kg is placed on a compressed vertical spring that is compressed .050m. (The spring and the block are not attached) The spring is released, and it propels the block vertically upward. when the block has risen .60m abovie its initial position, its velocity is 1.7 m/s. how much potential energy was originally in the spring?

    Set up an energy balance equation. Then go from there.

    First hint look into conservation of energy.

    Here are some formulas to look into

    PE=.5kx^2

    k=spring constant
    x=position

    KE=.5mv^2

    Combine them to form conservation of energy

    E=.5mv^2+.5kx^2
