2) Two blocks with masses M1 and M2 are connected by a massless string that passes over a pulley as shown. Mj has a mass of 2.25 kg and is on an incline of 49.5° with coefficient of kinetic friction µj = 0.205. M2 is on an incline of 35.5° with coefficient of kinetic friction µ2 = 0.105. The pulley can be modeled as a disk with a mass of 305 g and radius of 15 cm. When the system is released, Block M2 accelerates down the incline at rate of 0.52 m/s². (a) Determine mass of block 2 and the tension forces in the string connecting the blocks and the pulley. Draw accurate free body diagrams of both blocks and pulley, label each force correctly and show the steps in derivation of equations. (b) How much energy will be dissipated by friction 2 second after the blocks are released? M2 M 49.5° 35.5°
