A 1.3kg bike wheel, is spinning 190rpm clockwise when a student applies a frictional force as shown. The moment of inertia of any ring (such as the bike tire, 10cm neglecting the spokes) is I = mr2. Answer all questions realtive to the center of the wheel. What is the initial angular speed (in selectable units)? rad/s v How much torque does the friction cause? Nm v What is the moment of inertia? kg m2 v What is the angular acceleration? 1625 rad/s? v How long will the wheel take to stop spinning? How far will the wheel rotate before stopping? 2.4N rad revolutions
