energy problem.... I got a problem that goes likethis: Determine the energy required to accelerate a 1300 kg car from 10 to 60km/h on an uphill road with a vertical rise of 40m. Ok i know that work is the itegral of force which is ma. But what about this vertical rise of 40m? Does this basically mean at a 90 degree angle? Guess i just don't see the problem happening like that, but if that is what it means, that is what it means.
