Problem 15.31 Block A weighs 10 lb and block B weighs 4 lb. (Figure 1) Figure A (VB)₁ = 3 ft/s 1 of 1 B Part A If B is moving downward with a velocity (VB)₁ = 3 ft/s at t = 0, determine the velocity of A when t = 1 s. Assume that the horizontal plane is smooth. Neglect the mass of the pulleys and cords.
