Question
A 230-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
9.00 cm. Assume that the thread has negligible mass and does
not slip or stretch as it unwinds.
Determine the magnitude a of the pulley's
angular acceleration.
