Question
Block A (mass 40 kg) and block B (mass 80 kg) are connected by a string of negligible mass as shown in the figure. The
pulley is frictionless and has a negligible mass. If the coefficient of kinetic friction between block A and the incline is
Hk = 0.26 and the blocks are released from rest, determine the change in the kinetic energy of block A as it moves from C
to D, a distance of 15 m up the incline.
