## Homework Statement

A sim[le pendulum has a mass of .25kg and a length of 1.0m. It is displaced

through an angle of 15degrees and then released. What are (a) the maximum

speed, (b) the maximum angular acceleration, and (c) the maximum restoring

force? Solve the problem once by using the simple harmonic motion model for

the motion of the pendulum, and then solve the problem more precisely by

using more general principles.

## Homework Equations

## The Attempt at a Solution

The problem that I am having is getting started. I know this isn't

hard. I got the part (c) for the second on with the restoring force to be

mgsin theta = .634N and it is correct. I know the answer for the simple

models are close to the more precise ones but I can't find any way to

start.

Thanks for any help,

Kevin
