The system shown is at rest when a constant 250-N force is applied to block A. Neglecting the masses of the pulleys and the effect of friction in the pulleys and assuming that the coefficients of friction between block A and the horizontal surface are u, = 0.25 and H = 0.20, determine (a) the velocity of block Bafter block A has moved 2 m, (b) the tension in the cable.
