Suppose a yo-yo has a center shaft that has a 0.250 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 1.50 m/s2, what is the angular acceleration of the yo-yo?
(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. what is the tangential acceleration of a point on its edge? ans:
(a) 600 rad/s2,
(b) 450 rad/s,
(c) 21.0 m/s
