Box A (mass 50 kg) and box B (mass 200 kg) shown in Figure 8 are released from rest. Here the mass of pulleys is ignored. Ignore the friction between box A and box B, and the coefficient of copper friction between box B and slope is 0.2 degrees and the angle of slope is 20 degrees. Answer each of the following questions: 1) Calculate the acceleration (m/s^2) of box A. 2) Find the tension size (kgf). 3) When Box B moves 1.5m, calculate the speed (m/s) of Box B using Newton's 2nd law. 4) When box B moved 2m, calculate the speed (m/s) of box A using the modified energy supply law.
