You pull straight up on the string of a yo-yo with a force 0.31 N, and while your hand is moving up a distance 0.17 m, the yo-yo moves down a distance 0.30 m. The mass of the yo-yo is 0.069 kg, and it was initially moving downward with speed 2.2 m/s.
(a) What is the increase in the translational kinetic energy of the yo-yo?
(b) What is the new speed of the yo-yo?
(c) What is the increase in the rotational kinetic energy of the yo-yo?
