A flat-faced follower is driven using a circular eccentric cam rotating at a constant angular velocity $\omega$. At time $t=0$, the vertical position of the follower is $y(0)=0$, and the system is in the configuration shown below:
The vertical position of the follower face, $(y(t)$ is given by
1. $e \sin \omega t$
2. $e(1+ \cos 2 \omega t)$
3. $e(1- \cos \omega t)$
4. $e \sin 2 \omega t$
