Aweight with mass =250 gmw=250 g is tied to a piece of thread wrapped around a spool, which is suspended in such a way that it can rotate freely. when the weight is released, it accelerates toward the floor as the thread unwinds. assume that the spool can be treated as a uniform solid cylinder of radius =3.00 cmr=3.00 cm and mass =100 gms=100 g . find the magnitude of the acceleration of the weight as it descends. assume the thread has negligible mass and does not slip or stretch as it unwinds.
