1. The problem statement, all variables and given/known data 2. Relevant equations ƩF = ma = (mv2) / r 3. The attempt at a solution For part A: Fn - Fg = (mv2) / r Fn = ((mv2) / r ) + mg Fn = (500x20^2) / 10 + 500x9.8 Fn = 24900 This seems too high to be true. But I'm unsure of what I did wrong. I know the normal force is the force of which the track is acting on the car. For part B: I think it is just 20m/s but I'm not sure. I know an object traveling in a circle has the most speed when it's at the bottom of the circle. Thanks for the help in advance!
