a 1.0 kg wheel of radius 0.5 m is rotating at a rate of 40 rad/s about an axis through its center of mass. the mass of the spokes of the wheel can be neglected so that the mass is essentially concentrated at the rim. a force of 2.0 N is applied tangentially at the rim which brings the wheel to rest. through what angle did the wheel turn while it is being stopped?
