This one will stump most readers. The chemical potential energy in a certain amount of gasoline is converted to kinetic energy in a car that increases its speed from 0 mph to 32 mph. To pass another car the driver accelerates to 64 mph. Compared to the energy required to go from 0 to 32 mph, the energy required to go from 32 mph to 64 mph is

a) half as much
b) as much
c) twice as much
d) three times as much
e) four times as much

Well, I think it's a), or maybe b) or.... Anyway, I'd like to see the official answer now.
