A block of mass m is released from rest on the surface of a wedge which is inclined at an angle 6. The wedge has a mass M and is at rest on a horizontal table (Fig. 1). The coefcient of friction between the block and the wedge is #1 and that between the wedge and the table is Jug . The block slides down along the Fig. 1 wedge but the wedge remains at rest. (3) Find the maximum possible value of #1. [5 marks] (b) Draw a free-body diagram showing all the forces acting on the wedge. [6 marks] (0) Find the friction and the normal force acting on the wedge by the table. [7 marks] (d) Hence nd the minimum value of ,u2 for the wedge to remain at rest. [3 marks]
