Two blocks of masses m,= 4 kg and m2 = 6 kg are connected by a massless string that passes over a massless frictionless pulley as shown in figure 3.1. Initially, block m, lies on a rough horizontal plane while block m2 is at a height h =0.75 m above the ground. When the system starts from rest, m2 hits the ground with speed 2.8 m/s. Determine the acceleration of the masses, the tension in the string and the coefficient of kinetic friction between m, and the table.
