A block of mass m1 ϭ 2.00 kg and a block of mass m 2 ϭ 6.00 kg are connected by a massless string over a pul- ley in the shape of a solid disk having radius R ϭ 0.250 m and mass M ϭ 10.0 kg. These blocks are allowed to move on a fixed block-wedge of angle ϭ 30.0° as in Figure P10.37. The coefficient of kinetic friction is 0.360 for both blocks. Draw free-body diagrams of both blocks and of the pulley. Determine (a) the acceleration of the two blocks and (b) the tensions in the string on both sides of the pulley.
