Electricity is actually a very cheap form of energy. Suppose the cost of energy is 4 cents/kwh. First determine the amount of electrical energy which can be purchased for $11. Gas engines are about 36% efficient meaning that 36% of the energy received by the engine is converted to motion or kinetic energy. Assuming, 36% of the electrical energy of $11 worth of electricity is converted to kinetic energy of the car, how fast would a 3,000 kg car be moving in mi/hr (just Google the conversion to mph)?
