Homework Statement
(Sorry for my bad English)
A slippery (frictionless), light horizontal bar rotates about a vertical axis with a constant angular velocity ω. A cylinder with mass m, is initially attatched to a thread with length a and to a spring, which from the beginning has its "natural" length.
Suddenly the thread breaks. Now the maximum distance between the cylinder and the axis is b.
Determine the spring constant k for the spring.
I have uploaded a picture of the problem.
Thanks!
