A physics student spins a bucket of water over her head in a circular path in order to demonstrate centripetal force. She fills the bucket half-full with water first, and then empties out half of its contents (so that the bucket is a quarter-full) for her next trial. In which case is more force required to spin the bucket, and why? Explain using relevant force equation(s).

The first case requires more force to spin de bucket.

Explanation:

As we know, the centripetal force is directly proportional to the mass, the equation is given by:

The first case has a quarter more water than the second case, therefore the first case requires more force to spin de bucket.
