A solid sphere of radius = 8 cm and mass = 5 kg is sitting on a level table and is attached with a string over a pulley (radius = 2 cm and mass = .8 kg) to a hanging mass (m = 3 kg) which is 4 meters above the ground.
a) Calculate the Total work done on the sphere, pulley, block Wsphere, Wpulley, Wblock
b) Calculate the final angular and linear speeds of the sphere, w(angular speed)fsphere, vfsphere
