Question #49389

A pendulum has max displacement of A=2.5m and frequency=6Hz. Displacement at time x is x=Asin(wt).where A is max displacement and w is angular velocity 2pief.

Find time when displacement is 90cm.

Using a Power series expansion of above equation verify a time of 0.0416seconds for displacement to reach 250cm
