Consider a rotating bucket of water, spinning with constant angular speed w. After the system stabilizes, the water will be spinning at exactly the same rotational speed w.
a.) change to a rotating reference system and write the force F' that the water experiences in the rotating coordinate system.
b.) show that the force is conservative
c.) Find a potential energy associated with this force
