Alright, so recalculating without C1 and using 7100 as mg gives me 7570.27 ft/lbs, assuming my units are correct. Multiplied by the velocity, 29.3fps, gives me 221,809 ft/lbs/s, which converts to 403.289 hp. Does this sound correct?

Yes, C1 < 0. For the above scenario, it would be 0.35(29.3/35)=0.293

Using C1 reduces the magnitude of the answer pretty seriously. Are you saying that I should sub in mg*C0 for C1?

Ok so 7100 lbs is mg. that helps. And the C1 term has to be in there because rolling resistance increases with velocity. I guess C0 is what you have to overcome to begin moving

Homework Statement I working on this for a high school thesis. I am trying to find the power required to move a 7100 lb vehicle over a variety of scenarios, but am having trouble calculating the force of tractive resistance. Homework Equations I found what i thought was a pretty...
