A cylinder is fitted with a piston, beneath which is a spring, as in the drawing. The cylinder is open at the top. Friction is absent. The spring constant of the spring is 4100 N/m. The piston has a negligible mass and a radius of 0.023 m.

(a) When air beneath the piston is completely pumped out, how much does the atmospheric pressure cause the spring to compress?

(b) How much work does the atmospheric pressure do in compressing the spring?

    A) Pressure=Force/Area
    Solve for f, then plug F into
    solve for X

    B)work=change in enegy,
    measure SPE (spring potential energy)

    X is the answer from part A
