3. Tim attaches the string of a 0.10 kg yo-yo to his finger and releases the yo-yo from rest. As the yo-yo spins down, Tim keeps his finger motionless, which allows the yo-yo to be treated the same as a freely rolling object. After the yo-yo drops a distance of 0.90 m, it has a translational speed of 4.0 m/s and an angular speed of 180 rad/s. What is the moment of inertia of the vo-vo? Air resistance and friction are negligible
