Roller Coaster Design!

  1. Jan 7, 2008 #1
    I have an assignment in my highschool physics class to create a roller coaster that has at least one loop and a number of turns and drops. I have been searching the web to find a way to calculate if my car i made of K-Nex weighing 3oz, 85.04g, will have enough speed to clear a loop. The drop is about .8382m high, 2'9'', and i did find on another sight that the top of the loop cant be higher that half of the drop height. I guess i know it will clear the loop but i would like to know how fast it will be going, what angle the drop should be, and how fast the car will be traveling after it does clear the loop, if you have any information that would help me with my task i would apriciate that very much.

    thank you very much for your time.

    Welcome to PF, Shekels.
    Try doing a forum search on this subject to start with. There are some pretty good responses to previous threads about it. It seems to be a pretty popular school project these days.
