Question

below. Consider the system below. The pulley is massless and frictionless, and the string is massless. The mass of each block is ma = 5.0 kg, mo = 2.0 kg, mc = 4.0 kg, and md = 15.0 kg. The coefficient of kinetic friction is 0.35 for all surfaces. Mass mais initially in motion moving downward. a b с d a. Calculate the acceleration of the system? b. Calculate the tension in the string between block c and block d? c. Calculate the tension in the string between block b and block c? d.
