the equation is as thus fc = mv^2/r
OpenStudy (anonymous):
is fc = m * g?
OpenStudy (anonymous):
That equation is to find the centripidal force of an object

yes but can i use mg for fc
OpenStudy (anonymous):
so i would have mg = mv^2/r
OpenStudy (anonymous):
\[F _{c}=\frac{ mv^{2} }{ r }\]
OpenStudy (anonymous):
why would you want to do that? the question is asking for the force.
OpenStudy (anonymous):
OTL sorry

i had 5 hours of sleep this whole week so im not that clear-minded right now
OpenStudy (anonymous):

OpenStudy (anonymous):
junior year is not a happy year
OpenStudy (anonymous):
Same equation instead use the weight of the person not the weight of the car.

does the weight of the car now have nothing to do with it?
OpenStudy (anonymous):
im thinking about that one... actually i thnk its best to use both as the person is in the car as well
OpenStudy (anonymous):
okay, thank you very much!
OpenStudy (anonymous):
no prob but the answer I get is quite high so im trying to work out how many g's it is to see if its viable
OpenStudy (anonymous):
alright well i have to go to sleep i have a test tomorrow. gnight
