# The period of an elastic band

Assume that a mass is attached to an elastic band and then allowed to oscillate.

Would the formula for the period of oscillation be that as the same of the formula for the period of the oscillation for a spring.

T=2∏(√m/k) ?

Only if all the approximations you made concerning the spring when deriving this formula also apply to the elastic band.
