A yo-yo has a rotational inertia of 930 gcm2 and amass of 110 g. Its axle radius is2.9 mm, and its string is 130 cm long. The yo-yo rolls from rest down to theend of the string.
(a) What is the magnitude of its linear acceleration?
cm/s2
(b) How long does it take to reach the end of the string?
s
(c) As it reaches the end of the string, what is its linearspeed?
cm/s
(d) As it reaches the end of the string, what is its translationalkinetic energy?
J
(e) As it reaches the end of the string, what is its rotationalkinetic energy?
J
(f) As it reaches the end of the string, what is its angularspeed?
rad/s
