Two blocks are attached by a string of negligible mass which passes through a stationary pulley of negligible friction. The mass of the pulley is 4m, which in not negligible. The pulley can be approximated as a cylinder with Radius R. Block 13 is hanging in the air, but block A lies on an frictionless surface which is inclined at a 75o (α) with the vertical. Block B has a mass of m. Block A has a mass of 2m.

Express in terms of g, R and in .

A. the angular acceleration of the pulley

B. the rate at which A accelerates

C. the tension on the string
