It was best to assume an average speed because it gets really messy once you get past that point. I can do the calculation, taking in the slight decrease in potential energy, change from static to kinetic friction, etc. In short, nobody would get the answer and nobody would understand all the calculus that I would have to put on the site. Heck, there are not any formula symbols that I could use! The answer I gave is with in 1/1000th of your answers. That is good enough. It was a fun exercise and Rich won the wheels. Like I said, I will have more contests so other racers can win. Rich cannot play anymore. He already won a set of fully prepared wheels. ;D

Rich, Cyc, and Z, I still owe you wheels. Murph will keep his promise,though, rather late. Resend your address and wheel selection (PS or Limited). All my stuff is in South Beloit, IL. One of my lates is set-up in my apartment. When I get back, I will get the wheels out to you. Give me a little time. Murph is in Dallas, TX most of the time. Thx, Murph
