Constants v Part A Two masses, mA = 31.0 kg and m3 = 41.0 kg are connected by a rope that hangs over a pulley (as in the If the system is now released, use conservation offigure(Figure 1)). The pulley is a uniform cylinder of energy to determine the speed of mg just beforeradius R = 0.315 m and mass 3.7 kg . Initially, mA is on it strikes the ground. Assume the pulley is the ground and m B rests 2.5 m above the ground. frictionless. Express your answer using three significantfigures and include the appropriate units.
