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 175.0 kg and a radius of 2.500 m. A constant force of 40.0 N is applied tangent to the edge of the disk for 61.0 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.) α = rad/s2 (b) What is the final angular velocity of the stone? (Express your answer in vector form. Substitute numeric values, do not use variables.) ω = rad/s (c) Calculate the translational speed for a point on the edge of the stone after 61.0 s. m/s
