Two masses, mA = 32.0 kg and mB = 38.0 kg, are connected by a rope that hangs over a pulley (as in the figure below). The pulley is a uniform cylinder of radius R = 0.311 m and mass M = 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 mB just before it strikes the ground. Assume the pulley bearing is frictionless.

Transcribed Image Text:4. Two masses, mA = 32.0 kg and mB = 38.0 kg, are connected by a rope that hangs over a pulley (as in
the figure below). The pulley is a uniform cylinder of radius R = 0.311 m and mass M = 3.1 kg. Initially,
mA is on the ground and mp rests 2.5 m above the ground. If the system is released, use conservation
of energy to determine the speed of mB just before it strikes the ground. Assume the pulley bearing is
