A wedge of mass M rests on a rough horizontal surface with coefficient of friction µ. The face of the wedge is a smooth plane inclined at an angle θ to the horizontal. A mass A hangs from a light string which passes over a smooth peg at the upper end of the wedge and attaches to a mass B which slides without friction on the face of the wedge.
(i) Find the accelerations for the masses A and B, and the
tension in the string when µ is very large.
(ii) Find the smallest coefficient of friction for which the wedge
will remain at rest.
