A force F0of 400 lb is applied to block B. Letting the weights of A and B be 55 and 73 lb, respectively, and letting the static and kinetic friction coefficients between blocks A and B be µ1 = 0.25, and the static and kinetic friction coefficients between block B and the ground be µ2= 0.45, determine the accelerations of both blocks.
