and a radius of 1 m rotates on a frictionless axis perpendicular to the disk and through its center. A force of 10 N is applied tangentially to the rim. If the disk starts at rest, what is its angular velocity after 2 turns?
A stone of mass 9.5kg is hung vertically from the end of a rope that is wound around a pulley on a boat. The moment of inertia of the pulley is 0.47kg m
2
and the radius is 0.25m. The stone is released from rest and falls toward the water, causing the pulley to rotate. After the stone has fallen 2.5 m, what is the angular velocity of the pulley?
