I am having some problems with equations for a problem. The problem isnt really a question, it's more of finding equations to make something work. Basically, It is a graph on Microsoft Excel, that resembles a 2D track. The track has variable points that you can change, to increase height, distance, Coefficient of Friction, Centripetal Acceleration, Force Centripetal, etc. I have some equations figured out, but I am stuck on a few. Here is what i have and what i need, any help is appreciated. (remember there are no numbers, just equations)
The first is IE ( Initial Energy ) without Centripetal Acceleration added. I have no idea where to even start with this equation, but i assume that Initial Energy is the greatest kinetic Energy, minus the Kinetic Energy at the point you are? I need alot of help there. Final Equation: TE - KE
The second is IE of Individual Track segment with Centripetal Acceleration added. For this, I assume that it is once again the Total Energy minus the Kinetic Energy at that point plus ( Velocity^2 / Radius ) I dont know exactly how to get the radius though ( is it half of the track segment?? :confused: ) Final Equation: TE - KE + [v^2/(1/2)(TrackSegmentLength)]
The third is Speed with Centripetal Acceleration. For this I think I have it, but since i have Kinetic Energy as a Given, I would use the Equation v=SquareRoot(KE/.5m)
The fourth is Distance Traveled, for this, wouldnt it be the new track segment plus all of the previous track segments?? :confused: Final Equation: New Track + All Previous Track
That is all i have, please correct me on equations if I'm wrong, or if you need clarification id be glad to give it to you.
