The horizontal force P = 85 N is applied to the upper block with the system initially stationary. The block masses are mA = 19 kg and mg = 9 kg. Determine the magnitudes of the frictions forces F₁ (between block A and the ground) and F2 (between blocks A and B) for the following conditions on the coefficients of static friction: (a) ₁ = 0.37,₂ = 0.38 and (b) ₁ = 0.26,2 = 0.48. Assume that the coefficients of kinetic friction are 74 percent of the static values.
