A 240-g
mass hangs from a string that is wrapped around a pulley, as shown in the figure. The pulley is suspended in such a way that it can rotate freely. When the mass is released, it accelerates toward the floor as the string unwinds. Model the pulley as a uniform solid cylinder of mass 1.00 kg
and radius 7.00 cm.
Assume that the thread has negligible mass and does not slip or stretch as it unwinds.
