A block of mass m1 = 1.75 kg and a block of mass m2 = 5.90 kg are connected by a massless string over a pulley in the shape of a solid disk having radius R = 0.250 m and mass M = 10.0 kg. These blocks are allowed to move on a fixed block-wedge of angle ? = 30.0°. The coefficient of kinetic friction is 0.360 for both blocks.(a) Determine the acceleration of the two blocks.m/s2(b) Determine the tensions in the string on both sides of the pulley.left of the pulley Nright of the pulley N
