The string in a yo-yo is wound around an axle of radius 0.501 cm. The yo-yo has both rotational and translational motion, like a rolling object, and has mass 0.287 kg and outer radius 1.99 cm. Starting from rest, it rotates and falls a distance of 1.41 m (the length of the string). Assume for simplicity that the yo-yo is a uniform circular disk and that the string is thin compared to the radius of the axle.

(a) What is the speed of the yo-yo when it reaches the distance of 1.41 m?

___ m/s

(b) How long does it take to fall? [Hint: The translational and rotational kinetic energies are related, but the yo-yo is not rolling on its outer radius.]

___ s
