a 20.00-kg box is attached to a light string that is wrapped around a cylindrical frictionless spool of radius 15.0 cm and mass of 5.00 kg. The spool is suspended from the ceiling, and the box is then released from rest a distance 4.50 m above the floor.

What is the acceleration [in m/s2] of the box?

How long does it take [in s] for the box to reach the floor?

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....

A light, nonstretching cable is wrapped around a solid cylinder with mass 88 kg and radius 0.19 m. The cylinder rotates with negligible friction about a stationary horizontal axis. We attach the free end of the cable to a block of mass 48 kg, and release the block from rest at a distance 3.9 m above the floor. As the block falls, the cable unwinds without stretching or slipping. Find the angular speed of the cylinder (in radians/s) the moment...
