A wheel of radius R = 20.4 cm, mass M = 2.47 kg, and moment of inertia I is mounted on a frictionless, horizontal axle as in the figure. A light cord wrapped around the wheel supports an object of mass m = 0.514 kg. Calculate the angular acceleration of the wheel, the linear acceleration of the object, and the tension in the cord.
