1. The problem statement, all variables and given/known data Radius 150m, angle is 10 degree, mass of the car 800kg, speed 85 km/h. Find the normal force on the tires exerted by the pavement. ( There is friction) 2. Relevant equations [tex]\Sigma[/tex] F= m* v^2/r 3. The attempt at a solution The friction makes it's so complicated. I know that Fn= mg/cos10 will not work. Can anyone help me ?
