I have a simple math problem. I know the basic formula, but am too far removed from math lessons(50 years of age) to figure it out. I know you require like units to derive an answer.
A 200 gram object is rotated around a 4' radius at 100 mph. What is the centrifugal force?
I know(at least think) Fc=m*v²/r, but can't figure the units out to come to a clear enough answer.
If I use the 200 grams, would I need to convert the 100 mph to fps(147) or m/s(no clue at this time) and the r(4') to meters?
Or, to keep it simple(to me) could I just use say 8oz*147²/48" and yield ozs and divide by 16 to get pounds. I get 225 punds with this method and it seems like quite a lot of centrifugal force.
