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 answer

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
