Homework Statement
A thin metal disk of mass m=4.50 g and radius R=2.70 cm is attached at its center to a long fiber. When the disk is turned from the relaxed state through a small angle theta, the torque exerted by the fiber on the disk is proportional to theta.
Suppose the disk is twisted away from equilibrium by an angle of 27 degrees and released from rest. What is the maximum angular speed of the disk as it twists back and forth?
Homework Equations
w = sqrt(k/I)
t = -k(theta)
The Attempt at a Solution
So i found the first two parts of the problem fine but i am having trouble with this part. I am not sure where i can go with the given information
I converted the degrees to radians
27 degrees = .471239 rad
not sure what to do now
