Question 84: Oscillations

Question

The motion of a simple pendulum executing S.H.M. is represented by the following equation.
$$y = A\sin (\pi t + \phi )$$, where time is measured in second. The length of pendulum is

Accepted Answer

$$\omega  = \pi  = \sqrt {{g \over l}} $$
So, $$l = {g \over {{\pi ^2}}}$$
