The coefficients of friction between the three blocks and the horizontal surfaces are µs = 0.25 and µk = 0.20. The weights of the blocks are ωA =ωc = 20 lb, and ωB = 10 lb. Knowing that the blocks are initially at rest and that C moves to the right through 2.4 ft in 0.4 s, determine (a) the acceleration of each block, (b) the tension in the cable, (c) the force P. Neglect axle friction and the masses of the pulleys.
