The pulley is a uniform cylinder of radius R = 0.311 m
and mass 3.1 kg. Initially ma is on
the ground and mg rests 2.5 m
above the ground. If the system
is released, use conservation of
energy to determine the speed
of mg just before it strikes the
ground. Assume the pulley bearing
32.0 kg and mg = 38.0 kg, are con-
R
is frictionless.
