## Homework Statement

## Homework Equations

Spring motion equations

##\omega = \sqrt{\frac{k}{m}}##

##KE = \frac{1}{2}k \Delta x^2##

##F = -k \Delta x##

##T = \frac{1}{f}##

##f = \frac{\omega}{2 \pi}##

## The Attempt at a Solution

Part a is straightforward I believe.

Simply combine the masses as m+M, into ##\omega = \sqrt{\frac{k}{m+M}}##

So then ##T = \frac{1}{f} = \frac{2 \pi}{\sqrt{\frac{k}{m+M}}}##

I believe the time it takes to return equilibrium should half a period, so we get ##\frac{\pi}{\sqrt{\frac{k}{m+M}}}##

Part b is the tricky part, I'm not sure how one goes about it. I guess the first step would be identifying all the forces on the egg

The egg has an upwards normal force from the pan, along with a downwards force from gravity.

It would experience a force from the spring when it is being pulled up or down.

I imagine you would try to find the sum of forces and find when it is not in equilibrium?
