Suppose a yo-yo has a center shaft that has a 0.200 cm radius and that its string is being pulled. (a) if the string is stationary and the yo-yo accelerates away from it at a rate of 1.70 m/s2, what is the angular acceleration of the yo-yo in rad/s2? rad/s2 (b) what is the angular velocity in rad/s after 0.750 s if it starts from rest? rad/s (c) the outside radius of the yo-yo is 3.30 cm. what is the tangential acceleration in m/s2 of a point on its edge?
