Homework Statement
A bug crawls outward from the center of a compact disc spinning at 190 revolutions per minute. The coefficient of static friction between the bug's sticky feet and the disc surface is 1.4. How far does the bug get from the center before slipping?
Homework Equations
(static friction)(normal force)=(mv^2)/r
v=2pir/T
The Attempt at a Solution
I converted 190 rev/min into rad/sec, assuming that is how to find velocity. I got 19.89 rad/sec. I put (static friction)(mg)=mv^2/r equal to each other and got 14 meters as my r. However, this answer is wrong and I have no idea how else to solve this problem. Help please!
