1. The problem statement, all variables and given/known data 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? 2. Relevant equations newtons 3 laws 3. The attempt at a solution tanTheta = v^2/gR tan10 = v^2/(9.8 * 200m) v = 345 m/s^2 is this right?
