Two masses, mA and mB of equal mass of 2.09 kg, are connected by a rope that hangs over a pulley. The pulley is a uniform cylinder of radius R = 0.071 m and has a mass of 0.71 kg. Initially mA is on the table and mB rests 2.2 m above the ground and the static friction between mA and table is 0.21. Another mass mC was added onto mB side to make the sytem accelerate to 5.78m/s^2. Calculate a) [mass mC, b) the tension in the cord during the fall, c) the velocity just before hitting the ground, d) the inertia of the pulley e) angular velocity of the pulley just before the masses land on the ground. Assume the pulley bearing is frictionless, but the cord around the pully does not slip
