Your doing my homework for me?
The Cd and Crr for my car IS 0.32 and 0.01. I've already calculated it. As for finding a half mile constant slope hill... I'll work on it. I was just trying to set up something that could do the calculations for me and still be accurate. I was hoping you guys would change the time steps, maybe the weight of your car and info and see if it sounds correct.. or even if the calculations are correct. I wanted to start this project as an open source, anyone who wants to get involved can help, type of project since the variables can be changed and applied to all of us.
I'm sorry guys I had a different intention of starting this thread... to get us involved in a project together and work off of eachother to get ideas flowing and a program written. If yall are just wanting me to do everything and post my results, I will but if it has potential to be commercialized I'll be trying that out.
