Physics

A spring is hung from the ceiling. When a coffee mug is attached to its end, it stretches 3.0 cm before reaching its new equilibrium length. The block is then pulled down slightly and released.

What is the frequency of oscillation?

  1. Frequency = (1/2π)*√(k/m)

    k= mg/d N/m
    d= extension on spring

    So
    frequency = (1/2π)*√(mg/dm)
    =(1/2π)*√(g/d)
    =2.88 cycles/s
