## Homework Statement

a racecourse is designed with curves with a radius of 200m and a 10degree banking. What is the maximum speed a car can negotiate the curve without friction?

## Homework Equations

newtons 3 laws

## The Attempt at a Solution

tanTheta = v^2/gR

tan10 = v^2/(9.8 * 200m)

v = 345 m/s^2

is this right?
