Homework Statement
A small mass M attached to a string slides in a circle (x) on a frictionless horizontal table, with the force F providing the necessary tension (see figure). The force is then increased slowly and then maintained constant when M travels around in circle (y). The radius of circle (x) is twice the radius of circle (y).
1) M's kinetic energy at y is four times that at x.
2) M's angular momentum at x is ... that at y.
3) M's angular velocity at x is one quarter that at y.
4) As M moves from x to y, the work done by F is ... 0.
5) While going from x to y, there is no torque on M
