a) Two blocks are placed onto a frictionless in- clined plane at an angle of 23". The bottom block of mass ma a spring with spring constant of k = 690 N/m while while the top block of mass mA rests on top of it due to friction. The cocffi- cient of kinetic friction between the blocks is Hk, while the coefficient of static friction is 10.0 kg is in contact with 8.0 kg 23" a) Draw force diagrams for both blocks and the combined system. Make sure to appropriately label the action-reaction pairs. b) If the blocks are at rest on the incline, determine (6) The force of friction between the blocks and (1) the compression distance of the spring d.
