physics

A spring is resting vertically on a table. A small box is dropped onto the top of the spring and compresses it. Suppose the spring has a spring constant of 450 N/m and the box has a mass of 1.5 kg. The speed of the box just before it makes contact with the spring is 0.49 m/s.
(b) What is the magnitude of the spring's displacement when the spring is fully compressed?

  1. F = mg - kx
    ma = mg -kx
    when a equals zero
    kx = mg
    x=mg/k
    Plug and chug your numbers
