A string is wound around the rim of a uniform disk that rotates without friction about a fixed axis through its center. the mass of the disk is 3kg. and its radius is 25cm. The string is pulled with a force of 10N. What is the angular acceleration of the disk? If the disk is initially at rest, what is the angular velocity after 5s?

A string is wound around the edge of a solid 1.60 kg disk with a 0.130 m radius. The disk is initially at rest when the string is pulled, applying a force of 8.50 N in the plane of the disk and tangent to its edge. If the force is applied for 1.90 seconds, what is the magnitude of its final angular velocity?

A string is wound around the edge of a solid 1.60 kg disk with a 0.130 m radius. The disk is initially at rest when the string is pulled, applying a force of 8.75 N in the plane of the disk and tangent to its edge. If the force is applied for 1.90 seconds, what is the magnitude of its final angular velocity?
