How much energy (in ft-lbf, Btu, and kJ) is required to accelerate my 3400 pound car from rest to a velocity of 60 mph on a level stretch of road? If that event requires 7 seconds for completion, what is the average power (in both hp and kW) required for this acceleration? (If it's going uphill, why does it accelerate more slowly?) Assuming constant acceleration, how far did it travel?
