Question

An object of mass m is traveling in a circle with centripetal force Fc. If the velocity of the object is v, what is the radius of the circle?.

Answer 1

Hi there!

Recall the equation for centripetal force:
$F_c = \frac{mv^2}{r}$

We can rearrange the equation to solve for 'r'.

Multiply both sides by r:
$r * F_c = mv^2$

Divide both sides by Fc:
$\boxed{ r= \frac{mv^2}{F_c}}$
