Suppose you wish to whirl a pail full of water in a vertical circle without spilling any of its contents. If your arm is 0.93 m long (shoulder to fist) and the distance from the handle to the surface of the water is 15.0 cm, what minimum speed is required?

Answer 1

v^2/r=g
given r=.93+.15=1.08
solve for V.

Answer 2

That formula did work thanks!
