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).

Answer:

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:

[tex]F_{c}=ma_{c}[/tex]

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

I hope it helps you!
