The thermal energy stored in 1 kg of gasoline is about 10,000 kcal (42,000,000 J). A small car needs a forward force of about 500 N to move slowly at a constant speed on a leveled road (no change in ME). How far should the car go if all the energy stored in 1 kg gasoline is used in its motion?

Answer 1

well, 1J = 1N-m So, since you want meters,

42x10^6 N-m/500N = ? m
