What is the minimum angular speed required to keep water in a vertically revolving bucket if the rope radius is 0.77 m?

• 1.2 rad/s

• 2.5 rad/s

• 3.6 rad/s

• 4.9 rad/s

At which point in its vertical circular path is the water in the bucket most likely to spill out?

• At the bottom of the circle

• At the top of the circle

• Halfway up on the ascending side

• Halfway up on the descending side

When the bucket is at the top of its vertical circular path, and the water is just barely staying in, what force acts on the water/bucket system towards the center of the circle?

• Only the force of gravity

• Only the force of tension

• Both the force of gravity and the force of tension

• Neither the force of gravity nor the force of tension

Are you enjoying the video lesson?

• Yes

• No

What is the force of tension in the rope when the bucket is revolving at the minimum angular speed required to keep the water from spilling?

• Equal to the force of gravity

• Greater than the force of gravity

• Zero

• Negative
