This physics video tutorial explains how to calculate the acceleration of a system with a pulley attached to a mass on an inclined plane and another hanging mass using rotational dynamics. You need to write expressions for the net force of the two blocks using tension force, the weight force, kinetic friction, and the force of gravity parallel to the incline. You also need to write expressions for the net torque acting on the pulley / rotating solid disk. The net torque is the product of the rotational inertia of an object and its angular acceleration.
