Suppose a yo-yo has a center shaft that has a 0.290 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 1.40 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 3.20 cm. What is the tangential acceleration in m/s² of a point on its edge? m/s²
