A certain pulley is a uniform disk of mass 2.7 kg and radius 0.25 m. A rope applies a constant torque to the pulley, which is free to rotate without friction, resulting in an angular acceleration of 0.12 rad/s2. The pulley starts at rest at time t = 0 s. What is its rotational kinetic energy at t = 2.2 s?
A disk with a rotational inertia of 5kg*m^2 and a radius of 0.25 meters rotates on...
A disk with a rotational inertia of 5kg*m^2 and a radius of 0.25 meters rotates on a friction-less fixed axis perpendicular to the disk and through its center. A force of 2 Newtons is applied tangentially to the rim. After five seconds this force is removed and a braking force is applied. What amount of (tangential) braking force would be necessary to slow it down to a stop in two revolutions?

A large solid disk of radius 0.56 m freely rotates about a vertical frictionless axis at an initial angular speed of 8.3 rad/s. A small friction brake is used to bring the disk to rest in a time of 4.5 s by pressing the brake radially inward against the rim of the disk with a constant force of 36 N as shown in the figure below. The coefficient of friction between the brake and the disk is 0.4. Side View...
