I just would like to know If I am on the right track with this stuff. I have scanned the work I have done, sorry if it is a little messy. Disregard the top most $\ddot x$
A disk of radius
R but with no mass rotates anti clockwise at a constant rate $\omega$. Attached to a point on the edge of the disk is a simple pendulum of length
l and mass
m. Use Lagrange's method to find the equations of motion of the mass.
