Two blocks, A and B (with mass 42.0 kg and 84.0 kg , respectively), are connected by a string.The pulley is frictionless and of negligible mass. The coefficient of kinetic friction between block A and the incline is μk = 0.230. Determine the change in the kinetic energy of the system as block A moves from to C to D, a distance of 17.0 m up the incline (37 degrees above the horizon) if the system starts from rest.
Change in the kinetic energy of the system? I can't figure out the change, I went to the tutor: no help!?
Well i would take the quadasonic type of Block A and multiply that by Block B. The graphictomosphere of C and D are virtually irrelevant at this point so stick with the veronimostithicy of A and B and you'll find your answer.
