1. The problem statement, all variables and given/known data A 915kg car goes over a hill. If the radius of this curve is 43m, how fast must the car travel so that it exerts no force on the road at the crest. 2. Relevant equations Fc = mv^2/r Fg = mg 3. The attempt at a solution Fc = Fn+Fg Fn=Fg Fg=mg =(915)(9.81) =8976.15 Fc=????
