## Homework Statement

Fc = mv^2/r represents the motion of a simple pendulum. Describe how this data could be graphed so that the gradient of a straight line could be used to determine the velocity of the object.

## Homework Equations

Fc = mv^2/r

## The Attempt at a Solution

I'm kinda stumped. I tried graphing Fc vs r and got nowhere. Kinda attempted @ m =0.5, r =1, Fc = v^2/2 and thus when you derive Fc with respect to v, the gradient function = v, and thus the gradient of any tangent through the curve would give the value of the velocity at that point. Didn't really make sense to me

UPDATE: tried graphing Fc vs v^2 and got a straight line. realised the slope gives m/r. not sure if this is any helpful info but pls need help on the ASAP :) thankssss
