Power(hp) needed for climbing an inclined plane

[James Chartrand]

how much power(hp) would a 1-ton tracked vehicle need to climb 40° hills at 10kph. I know that this isn't exactly a physics question but I know that solving it involves physics to a certain extent.

It is completely a physics question, but it is of a form where it is required, on this forum, that you make some effort on your own. What is your background? What is your need to figure this out? I assume you are implying that this is not a homework question.

I am sorry for my lack (no) of content in describing the need for this question- the reason for which it that I didn't have much time to post it- and error that I will rectify now. The reason that I posted this is because I am building a 1:4 recreation of an M4 Sherman tank- of course, it won't be nearly as heavy as the real thing- but still a formidable 1000 lb. I want to equip it with an internal combustion gasoline engine and I would like to know the power needed for it.

I think that's a lot more complicated that your fairly straight-forward question suggests. You'll have to take into account the efficiency of transfer of power from the engine to the treads at the very least.
