Question
A large stone disk is viewed from above and is initially at rest as seen in the figure below. The disk has a mass of 120.0 kg and a radius of 2.100 m. A constant force of 40.0 N is applied tangent to the edge of the disk for 58.0 s, causing the disk to spin around the z axis.
(a) Calculate the angular acceleration of the stone, finding both the direction and magnitude. (Express your answer in vector form. Substitute numeric values, do not use variables.)
(b) What is the finalangular velocity of the stone? (Express your answer in vector form. Substitute numeric values, do not use variables.)
