1. The problem statement, all variables and given/known data

A simple pendulum of mass m and lenghth l is suspended in a car travelling with a constant speed v around a circle of radius r.If the pendulum undergoes small oscillations about its equilibrium position, what will be the frequency of the oscillations??
2. Relevant equations

$$n=1/2\pi (\sqrt{l/g}$$)
$$mv^2/r =mg$$
3. The attempt at a solution
