uniform solid disk is mounted on an axle in such a way that it is free to rotate about a horizontal axis. The radius of the disk is 0.450 m and its mass is 22.0 kg. As shown the diagram, two forces F, = 93.0 N and F, = 150 N applied to the disk sets the disk rotating with a constant angular acceleration. Assume the axle is frictionless. (a) Calculate the magnitude and direction of the net torque produced by the two forces. magnitude N. m direction --Select-- (b) Determine the magnitude of the angular acceleration of the disk. rad/s2
