A uniform cylinder of mass m and radius R is pivoted on frictionless bearings. A string of negligible mass is wrapped around the cylinder with the other end connected to a mass M. The system is released from a height h above the incline’s bottom (see figure). Find (a) the block's acceleration in terms of g, θ, m, and M and (b) the tension in the string in terms of g, θ, m, and M.

It is a triangular slope with a pulley at the top.
