1. The problem statement, all variables and given/known data A curve of radius 139 m is banked at an angle of 11°. An 866-kg car negotiates the curve at 89 km/h without skidding. Neglect the effects of air drag and rolling friction. Find the following. (a) the normal force exerted by the pavement on the tires 2. Relevant equations there is no set eqution for Normal force 3. The attempt at a solution I would assume that the normal force would be mgcos(theta) after making a free body diargram because mg is straig down, and the normal is pointed perpindicular to the 11 degree road, so to find fn I would say cos(theta)= fn/mg, and then mgcos(theta)is equalto fn, but the answer is (mg)/cos(theta). This equation would suggest that the normal force is greater than the weight force which makes no sense no me. Why is mg/cos(theta) correct?
