A 30-kg block is getting pulled up a steep slope under a constant acceleration with a force of FD = 3.2v + 220, where Fp is in N and v is in m/s. Determine the acceleration and coefficient of friction if the block was displaced from rest to a point s = 30m away from its original position after being pulled for t = 7.5 s. The angle of inclination is 0 = 25. F
