A 4.5-kg block is hung from a spring causing the spring to elongate 12 cm. With what period will the spring oscillate if the spring was stretched 15 cm and released?

  • physics -

    for your other mass/spring problem I derived:

    (2 pi f)^2 = k/m

    same here
    to get k:
    F = weight = 4.5 * 9.81 = 44.1 N
    deflection = .12 m
    so k = 44.1/.12

    now solve for f = (1/2pi)sqrt(k/m)
    and
    T = 1/f
