(a) If the yo-yo’s moment of inertia is increased, does the final linear speed increase, decrease, or stay the same? Explain. (b) Find the final linear speed for the case I = 3.5 * 10-5kg · m2. [Answer: (a) Increasing the moment of inertiaincreases the rotational kinetic energy, and leaves less energy for the translational kinetic energy. As a result, the linearspeed decreases. (b) v = 0.84 m>s]
