The mass moment of inertia of the 60-kg spool about its mass center G is 1.35 kg · m2. The spool is at rest on the horizontal surface when the constant force P = 200 N is applied to the cable that is wound around its hub. Calculate the angular velocity of the spool 2 s later, assuming that the static as well as the kinetic coefficient of friction between the spool and the surface is (a) μ = 0.2; and (b) μ = 0.1.
