A yo-yo has a rotational inertia of 1080 g·cm2 and a mass of 140 g. Its axle radius is 2.5 mm, and its string is 110 cm long. The yo-yo rolls from rest down to the end of the string.
(a) What is the magnitude of its linear acceleration?
(b) How long does it take to reach the end of the string?
(c) As it reaches the end of the string, what is its linear speed?
(d) As it reaches the end of the string, what is its translational kinetic energy?
(e) As it reaches the end of the string, what is its rotational kinetic energy?
(f) As it reaches the end of the string, what is its angular speed?
