Tension and acceleration of a falling cylinder on a rope

[bluejay]

one end of a weightless rope is tied to the ceiling of a building and the other end is wrapped around a uniform solid cylinder that has a radius R and mass M. The cylinder is then released and falls toward the floor. The moment of inertia of a solid cylinder about an axis through its center of mass is: I=0.5MR^2

a.find the tension T in the string

b. what is the acceleration of M?

I haven't checked the rules of the forum for a while, but I don't think they've changed. You have to start showing us how you tried to solve the problem.
