# Homework Help: Simple Pendulum Angle problem

1. Aug 2, 2005

You pull a simple pendulum of length 0.215 m to the side through an angle of 3.50 ^\circ and release it.

i got 0.93, but it marked it wrong. i divided the mass over the accel of gravity, squared it and multiplied by 2pi. is this wrong?

oh sorry

How much time does it take the pendulum bob to reach its highest speed?
Take free fall acceleration to be g = 9.80 m/s^2.

The pendulum will be at it's highest speed when it is at the bottom of it's swing.

Also, the equation for the period of a pendulum is $$T = \sqrt \frac {m}{g}$$
