The coefficients of friction between block B and block A are µs = 0.12 and µk = 0.10 and the coefficients of friction between block A and the incline are µs = 0.24 and µk = 0.20. The masses of block A and block B are 10 kg and 5 kg respectively .Knowing that the system is released from rest in the position shown, determine (a) the acceleration of A, (b) the velocity of B relative to A at t = 0.5 s.
