A small block of mass m2 is placed on top of a large block of mass m1 at rest on a horizontal surface. A force, F, is applied to the large block such that it accelerates forward. Part A) Given the coefficient of kinetic friction between the large block and the horizontal surface, μK, and the coefficient of static friction between the two blocks, μS, determine the maximum value of the applied force that can be exerted before the small block starts sliding from its position of rest relative to the large block Part B) Given that m1 = 20 kg, m2 = 5 kg, , μK = 0.70, and μS = 1.4, determine (1) the numerical of F and (2) the time it would take for the system to move 2.5 m/s faster.
