Question

A weight with mass mw=150 gmw=150 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 R=4.00 cmR=4.00 cm and mass Ms=100 gMs=100 g . Find the magnitude aa of the acceleration of the weight as it descends. Assume the thread has negligible mass and does not slip or stretch as it unwinds.

Use g=9.81 m/s2.

a= m/s2

Find the tension T in the thread.

T= N
