1. The problem statement, all variables and given/known data A hump backed bridge is in the form of a circular arc of radius 35m. What is the greatest speed with which a car can cross the bridge without leaving the ground at its highest point? 2. Relevant equations F = m v2/r = mrω2 3. The attempt at a solution I've tried using the equation above but no speed, angular velocity or mass is given. Am I missing something?
