1. The problem statement, all variables and given/known data A car, which weighs 1000 N, travels over a bumpy road with a constant speed. Gravity acts. The road at point B is in the shape of a circle with a radius of 100 meters. http://online.physics.uiuc.edu/cgi/courses/shell/common/showme.pl?courses/phys211/oldexams/exam1/sp08/fig21.gif [Broken] Which one of these statements correctly relates the force of the car on the road at points A (a valley) and B (the top of a hill)? (a) The magnitude of the force of the car on the road is larger at point A than it is at point B. (b) The magnitude of the force of the car on the road is larger at point B than it is at point A. (c) You need to know the road radius at point A to answer this question. 2. Relevant equations a = v^2/r^2 = w^2*r 3. The attempt at a solution I thought at the point A, it's considered as the lowest point of circular path, while the point B is considered as the highest point. So, at A Weight is somewhat canceled with the tension(thinking about uniform circular path) but at B weight is added to the tension.. That's why i thought B has larger force than at point A.... What's wrong in my attempt..? Please help me out here.... Thanks.
