## Homework Statement

The tumbler in an upright clothes dryer rotates at a critical angular

velocity so that clothes passing over the top briefly experience weightlessness.

If the radius of the drum is 0.30 m, what is this critical rotation rate? (Express

your answer in both radians per second and revolutions per min (RPM).) At

this rate, what is the apparent gravity felt by the clothes when they pass over

the bottom? (Express your answer in multiples of g.)

## Homework Equations

a

_{rad}=v

^{2}/R

## The Attempt at a Solution

I don't see how we can extrapolate a critical rotation rate from the given equation. Maybe I am just missing something or are we looking for V

_{f}?
