Block B of weight 18 lb is initially at rest as shown on the upper surface of a 45-lb wedge A which is supported by a horizontal surface. A 4-lb block C is connected to block B by a cord, which passes over a pulley of negligible mass. Using computational software and denoting by µ the coefficient of friction at all surfaces, calculate the initial acceleration of the wedge and the initial acceleration of block B relative to the wedge for values of µ ≥ 0. Use 0.01 increments for µ until the wedge does not move and then use 0.1 increments until no motion occurs.
