Thanks. Well I figured since it's being stretched, the restoring force of the spring might be why it's rotating. It has some rotational kinetic energy, and we can find that because we're given omega. It also has some spring potential energy. There's a force radially inward with magnitude mv^2/R...
Homework Statement
An astronaut on a spacewalk loses her grip on a circular garter spring (pictured below). Looking at the spring she notices that it is rotating around its axis of rotational symmetry at a rate of 300 rpm. The circumference of the rotating garter spring is 1% longer than that...
