The moment of inertia of a certain cylinder, whose mass is not distributed uniformly, is 0.6mR² about its geometric axis. The translational speed of the center of mass after it starts from rest and rolls 14 m down a 30°incline is approximately A) 9.3 m/s. B) 86 m/s. C) 13 m/s. D) 3.1 m/s. E) 41 m/s.
