Each of the plates A, B, and C have a mass of 10 kg. Plate A is on the bottom, plate B is in the middle, and plate C is on the top. Plate A is being pulled to the right with a force of 15 N, Plate B is being pulled to the let with a force of 100 N, and Plate C is being pulled to the right with a force of 18 N. The coefficients of static and kinetic friction are 0.3 and 0.2, respectively, between each of the plates and between plate A and the ground. Determine the acceleration of each plate.
