NOTE: For this question, see figure 11-35 on page 306 of your textbook. Mass mA = 7.16 kg sits on a frictionless, horizontal surface. A massless string is tied to mA, passes over a pulley (a solid disk of mass Mp = 1.42 kg and radius Rp = 68.5 cm), and is tied to mB = 4.95 kg hanging in space. Assume:- the system starts from rest- the string does not slip on the pulley- the string is always perpendicular to the radius of the pulley a) Find a, the magnitude of the acceleration of the masses. m/s2 b) Find v, the speed of the masses after mB has fallen distance h = 8.52 m. m/s c) Find W, the work that has been done on the pulley after mB has fallen distance h = 8.52 m J
