mg<=mv^2/r

v>=sqrt(g*r)

check that.

**Young J. Hong**, Friday, February 15, 2013 at 5:17pmConsider the following equation in the y-direction.

Fy=T+Fg=ma

Or in this case...

T+Fg=(mv^2)/R

Tension equals to 0 because when the pail of water is at the highest point, tension is nonexistent.

Therefore...

mg=(mv^2)/R

Cancel out mass

g=(v^2)/R

(Rg)^(1/2)=v

Plug in values.
