Change in Kinetic Energy as Block moves up Incline and starts from rest

cll123

1. The problem statement, all variables and given/known data
Two blocks, A and B (with mass 20.0 kg and 40.0 kg , respectively), are connected by a string, as shown in Figure P5.64. The pulley is frictionless and of negligible mass. The coefficient of kinetic friction between block A and the incline is μk = 0.290. Determine the change in the kinetic energy of the system as block A moves from to C to D, a distance of 19.0 m up the incline if the system starts from rest. (The angle above the horizontal is 37 degrees)
