13-26. At a given instant the 10-lb block A is moving downward with a speed of 6 ft/s. Determine its speed 2 s later if block B has a weight of 4 lb, and the coefficient of kinetic friction between it and the inclined plane is µk = 0.2. Neglect the mass of the pulleys and cord. Prob. 13-26 B 000 30° A 000€
