## Homework Statement

Curve radius is 230 meters and friction value between car tires and road is 0.87. Find the maximum speed of a car that wants to successfully pass through that curve.

## Homework Equations

Friction force = k * N

Perimeter of a circle = 2 * pi * r

F = m * g

w = (f-f0)/t

a = r * w^2

## The Attempt at a Solution

I know how to solve this exercise when I have the mass of a car and the time of travel. In this situation I tried to assign variables X and Y to both mass and time, but still didn't manage to find the correct answer.

PS. Correct answer should be 44 m/s.
