A yo-yo has a centre shaft with a radius of 0.350 cm and an outer radius of 2.50 cm. The string of the yo- yo is stationary and the yo-yo accelerates away from it at 2.50 m/s. Question 3 (a) If the yo-yo starts from rest, what is the angular velocity of the centre shaft after 0.850 s? (b) What is the angular velocity of the outer edge of the yo-yo after 0.850 s? (c) Through what angle does the central shaft rotate in 0.850 s? Enter your answer in radians. (e) What is the tangential acceleration of the outer edge?
