In Example 8-10, mass m1 = 2.40 kg is connected to mass m2 = 1.80 kg as shown. Suppose the two masses start from rest and are moving with a speed of 1.95 m/s just before m2 hits the floor. (a) If the coefficient of kinetic friction is µk = 0.320, what is the distance of travel, d, for the masses? cm (b) How much conservative work was done on this system? J (c) How much nonconservative work was done on this system? J
