I am stumped on the following and am looking for a good way to think
about the problem.
A uniform disk of mass M and radius R has a massless, thin thread
wrapped around the rim and this thread is pulled by a constant force in
the plane of the disk. This force is the net force acting on the disk
(ie in deep space away from any other masses) . What is the linear
acceleration of the CM of the disk and what is the angular acceleration
about the CM caused by this force?
How do the answers change if it is a uniform hoop?
Thanks for some direction on getting at these questions.
