[SOLVED] just a problem that I'm stuck on.. 1. The problem statement, all variables and given/known data A car travels around a curve with a radius 55.0 m at a speed of 20.0 m/s. At what angle must the curve be banked so that the car does not have to rely on friction to remain on the road? 2. Relevant equations tan[theta] = FC/FG tan[theta] = v^2/rg 3. The attempt at a solution there is no solution..I'm confused.. I tried rotating the equation on a different but rather same question..and I can't figure it out.. when got the answer, i tried transposing tan to the other side..it got me more confused..
