Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I have this problem:

A simple pendulum of lengthLis suspended from the ceiling of an elevator. The elevator is accelerating upward with accelerationa.

What is the period of this pendulum?

From logic I know that T=2pi*sqrt(L/(g+a)), but when I try to find it .. I failed.

Please can I have some help to find the period ?
