height in meter * mass of the car in kilograms * 9,81 (speed of light) - friction (10%) = speed in meters per second
I'm glad we dont need to take g force into consideration here. Also i never knew 9,81 was the speed of light....9,81 mega metres per month? Units? Also it would be quite intresting to try to derieve meters per second from height (metres) and mass (kg). You could have kgm-1 but ms-2? You need to put time in there also. I am surprised, if not shocked that you got a C+ in physics
Furthermore, TConwell there is no need to complain about coasterboaster spamming when i see you doing a fair share of the offending in this thread too. In defence of coasterboaster he is just trying to keep the forums alive and he is doing a good job in my opinion.
As for the actual question. Speed is better than height hands down. One word...Nemesis...well any ride at Alton Towers
