Two masses (mA = 4 kg, mB = 10 kg) are connected via a light string around a solid disk frictionless pulley (mp = 1 kg, rp = 20 cm). The coefficient of static and kinetic friction among all sur- faces is 0.2 and 0.1 respectively. The angle 1 = 30o while 2 = 55o. (a) What is the angular acceleration of the disk? (b) What is the tension in the string on both sides of the pulley? If the sys- tem starts from rest, (c) how far does block A travel in 3 s and what is the (d) angular velocity of the disk?
