9. A spring has a force constant of 100 N/m and an
unstretched length of 0.07 m. One end is attached to
a post that is free to rotate in the center of a smooth.

The other end is attached to a 1kg disc moving in
uniform circular motion on the table, which
stretches the spring by 0.03 m. Friction is negligible.
