Good Evening to all,(adsbygoogle = window.adsbygoogle || []).push({});

I have been working on the following problem for the past several days and have finally come to the end of my rope. I hate to admit defeat but I do need some help. I'm almost certain I'm simply missing something thats embarassingly simple....

This is the problem exactly as it appears on the page:

----------------------------------------------------------------------------

2. Centrifugal force is given by the following equation:

F = m [tex]\omega[/tex]^2 r

Where F = Centrifugal force

m = mass

[tex]\omega[/tex] = angular velocity

r = length of radius

A student told me the other day that centrifugal force on a mass m kg, rotating at an angular velocity of [tex]\omega[/tex] rpm and at a radius of r feet, is given by the following equation:

F = 3.342 x 10^-3 m [tex]\omega[/tex]^2 r [Newtons]

Are both equations correct? Explain?

----------------------------------------------------------------------------

I know that this means I need to take the F equation, break it down into its base SI units and build it back up taking the meters to feet and seconds to minutes conversion into consideration.

I know that the conversion for meters to feet is 3.28084. What am I missing?
