Suppose a yo-yo has a center shaft 0.300 cm in radius and that string is being pulled from it.
(a) If the string is stationary and the yo-yo accelerates away from it at a rate of 1.70 m/s^2, what is its angular acceleration?
(b) What is the angular velocity after 0.750 s if it starts from rest?
(c) The outside radius of the yo-yo is 3.50 cm. In the reference fram of the yo-yo's mass center, what is the tangential acceleration of a point on its edge?
