2. A block of mass m, = 20 kg which lies on an incline frictional surface is connected to another block of mass m, = 100 kg by two massless ropes and two massless, frictionless pulleys as shown in Fig. 1. The inclined surface makes 30° angle with the horizontal line. The coefficient of kinetic friction between the block m, and the inclined surface is 0.12. m, =30° Fig. 1 Draw the free body diagram of block m, block m, and the hanging pulley. Find the accelerations of block m, and block m,. Calculate the tensions in the two massless ropes.
