A collar of mass m is initially at rest on a horizontal arm when a constant moment M is applied to the system to make it rotate. Assume that the mass of the horizontal arm is negligible and that the collar is free to slide without friction.

Derive the equations of motion of the system, taking advantage of the angular impulse-momentum principle. Hint: Applying the angular impulse momentum principle yields only one of the needed equations of motion.
