@Abhisar

OpenStudy (abhisar):

\(\sf \huge \frac{mv^2}{r}\)

OpenStudy (anonymous):

whats v?

OpenStudy (abhisar):

velocity

OpenStudy (anonymous):

but i don't know the velocity

OpenStudy (abhisar):

is centripetal force given?

OpenStudy (abhisar):

what's you actual question?

OpenStudy (anonymous):

i have the mass in kg, the radius(m), and the times for 20 revolutions. I have to find centripetal force, period, circumference, velocity and velocity^2

OpenStudy (anonymous):

The actual question is: Is the relationship between velocity and centripetal force a direct, linear relationship or is it a nonlinear square relationship? Explain the answer using your graphs of F vs. V and F vs. V^2. What is the precise mathematical relationship between velocity and centripetal force
