Answer to Question #258370 in Physics for Mule

Question

water is not to spill, what is the minimum velocity the pail can have? (b) How much time per revolution is this equivalent to? 

Answer 1

The minimum velocity $v$ is defined by the conditions required for the water not to spill. This is equivalent to the following value of time per revolution:

$$t=\frac 1n=\frac{2\pi}\omega=\frac{2\pi r}{v}.$$
