The Bucket (Posted on 2006-09-28) Difficulty: 2 of 5
Consider a bucket of water with two holes of equal area through which water is discharged. The water can flow out through hole ( B ), at the bottom, or through the down-spout, which begins at the top ( T ) and has its opening the same distance below the water level as the center of hole ( B).

Ignoring any friction effects, out of which opening will the water flow faster, and why?

I agree with you and others - no free fall here. This is somewhat irrelevant but here is an interesting question: If we have a vertical pipe filled with water and a cork on the top, and we open the bottom, what would be the speed of the cork with time? Obviously it is not constant since initially it is zero. What if the diameter of the pipe gradually increases from the top to the bottom? At what point it will become a free fall?
