    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


    k=spring constant


    Combine them to form conservation of energy
