Homework Statement
A spring has a force constant of 548 N/m and
an unstretched length of 6 cm. One end is
attached to a post that is free to rotate in the
center of a smooth table, as shown in the top
view below. The other end is attached to a
8 kg disk moving in uniform circular motion
on the table, which stretches the spring by
4 cm.
Note: Friction is negligible.
1. W = 8.26365 J
2. W = 4.13182 J
3. W = 1.3152 J
4. W = 0.00473472 J
5. W = 0 J
