    Using Normal Force on inclined plane vs banked curve

    On an inclined plane, "\SigmaFy = N - mg cos ø = ma = 0". And "\SigmaFx = mg sin ø = ma" (frictionless). So, in the y direction, "N = mg cos ø". But on a banked curve, "\SigmaFy = N cos ø - mg = ma= 0". And "\SigmaFx = N sin ø = ma = mv²/r" (frictionless). So, in the y direction, "N cos...
