20. A 5 kg mass is placed on a 35 degree inclined plane as shown with a coefficient of kinetic friction of 0.10. The 5 kg mass is attached to a pulley with a hanging mass of 12 kg, and as a result, the 5 kg mass is pulled up the inclined plane. a) Draw two free-body diagrams; one for each of the masses. On each free-body diagram, indicate the positive direction that you will use for your equations. b) Use Newton's second law to set up equation(s) for the two blocks. c) Determine the acceleration of the system. d) Determine the magnitude of tension in the rope.
