Friction less Banked curve

  1. Jun 1, 2007 #1
    Hey I am doing a assignment on Roller coaster physics and i am to design a Roller coaster taking all the aspects of physics.

    I am stuck at my banked curve i dont know what formula to use to find the angle of the curve.
    I have seen this formula in the forums
    Tan theta=v^2/rg

    but the thing is i dont know how that formula was derived so i cant useit in my assigment unless i know how it was made.

    So if someone know how to make that formula or another forumula i can use please could you post it. Thanks

    ahh ya and i for got to say that you can ignore friction.

    Welcome to PF, Newme. I can't help you with any math stuff; I'm more of a 'hands on' guy. (No one would get on my rides in Rollercoaster Tycoon. :frown:)
    You are definitely in the right place to get the answers, though. Just hang tight and the experts will show up like rock bass on a dead minnow.

    Thanks for that!!
    Ok so know with this formula
    Velocity max=sqaure root (rg tan theta)
    can be rearanged to tan theta=v^2/rg
    thanks for the help on that
