12.124 Block A has a weight of 40 lb, and block B has a weight of 8 lb. The coefficient of kinetic friction between all surfaces of contact is μ = 0.15. Knowing 0 = 20° and P = 50 lb, determine (a) the acceleration of block B, (b) the tension in the cord. Answer (a) 21.0 ft/s2 & 37.9°, (b) 14.61 lb.
