A spool of thread with a mass of m = 0.1 kg and radius of 5 cm has one end tied to a rod while being held at rest. The spool is then dropped and rotates while falling 0.6 meters to the floor. Just as it hits the floor the spool is rotating with an angular speed of w= 55 rad/s. Please consider the sting mass as negligible and that it comes off tangential to the spool. a) Find the...

A 150-g weight 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 3 cm and mass Ms 100 g. Find the tension in the thread and the magnitude of the acceleration of the weight as it descends....

A solid disk of mass m = 9.2 kg and radius R = 0.2 m is rotating with a constant angular velocity of w = 38 rad/s. A thin rectangular rod with mass m2 = 3.7 kg and length L = 2R = 0.4 m begins at rest above the disk and is dropped on the disk where it begins to spin with the disk. 1) What is the initial angular momentum of the rod and disk system? kg-m2/s Submit...

A DVD of mass M = 20.0 g = 0.0200 kg and radius R = 6.00 cm = 0.0600 m is rotating freely around a fixed vertical axis without any friction. Its initial angular velocity is ?1= 102 rad/s. A bug of mass m = 6.00 g = 0.00600 kgdrops onto the center of the rotating DVD. The bug then walks radially outward toward the edge of the DVD without slipping until it reaches a distance r from the center,...
