Two masses, m1 = 18.0 kg and m2 = 26.5 kg, are connected
Chapter 2, Problem 49P(choose chapter or problem)
(III) Two masses, \(m_{1}=18.0 \mathrm{~kg}\) and \(m_{2}=26.5 \mathrm{~kg}\) , are connected by a rope that hangs over a pulley (as in Fig. 8-47). The pulley is a uniform cylinder of radius 0.260 m and mass 7.50 kg. Initially, \(m_{1}\) is on the ground and \(m_{2}\) rests 3.00 m above the ground. If the system is now released, use conservation of energy to determine the speed of \(m_{2}\) just before it strikes the ground. Assume the pulley is frictionless.
