A block of mass m = 10 Kg is attached to a cable that wraps around the pulley. The pulley is pivoted at the center, and the angle of incline is θ = 30°. The radius of the pulley is R = 0.5 m and its moment of inertia is I = 0.4 Kgm2. The block is released from rest and slides down the ramp, and the coefficient of friction is μk= 0.2 between the block and the ramp.

(a) Find the acceleration of the block. a = _______________________

(b) Find the tension in the cable. T = ______________________

I have no idea where to start.
