hanging mass has a mass, m = 19g, the wheel has a radius, R = 0.10m, and the wheel and axle has a moment of inertia, IWA = 4.70x10-3 kg·m2. If the pulley's moment of inertia and friction on the axle are negligible, determine
(a) the tension in the string and
(b) the acceleration of the hanging mass.
