  1. loss of gravitational potential energy
    = m g * change in height
    = 5 * 9.81 *(2 + .25)
    = 110 Joules
    that is now stored in the spring (1/2)kx^2
    so
    (1/2) k (.25)^2 = 110

    k = 3532 N/m

    If you stand on a bathroom scale, the spring inside the scale compresses 0.50 mm, and it tells you your weight is 680 N. Now if you jump on the scale from a height of 1.4 m, what does the scale read at its peak?
