A wooden block of mass m1 3.2 kg and a hollow block of mass m2 = 8.7 kg are connected bý a rope which runs over a friction-less pulley. Assume that the pulley is a solid iron disc with a radius R = 0.3 m and mass M = 5.1 kg. The ramp is wedge- shaped and makes an angle of 0=36°. The coefficient of kinetic friction is 0.29 for both blocks and the wedgeshaped incline. %3D

A wooden bldck of mass m, = 3.2 kg and a hollow block of mass m2 = 8.7 kg are
connected by a rope which runs over a friction-less pulley. Assume that the pulley is
a solid iron disc with a radius R = 0.3 m and mass M = 5.1 kg. The ramp is wedge-
shaped and makes an angle of 0=36°. The coefficient of kinetic friction is 0.29 for
both blocks and the wedgeshaped incline.
(a) Draw force diagrams of both blocks and of the pulley.
(b) Determine the acceleration of the two blocks.
(c) Determine the tensions in the string on both sides of the pulley.
