A solid wheel on a game show is given an initial angular speed of 1.25 rad/s in the counterclockwise direction. It comes to rest after rotating through 3/4 of a turn. Find the torque exerted on the wheel given that it is a disk of radius 0.73 m and mass 6.4 kg. I got 0.5654 as the answer, but it's not correct. Anyone able to help?
