Suppose it takes 75 kW of power for your car to travel at a constant speed on the highway.
(a) What is this in horsepower?
(b) How much energy in joules would it take for your car to travel at highway speed for 5.0 hours?
(c) Suppose this amount of energy is to be stored in the electric field of a parallel-plate capacitor (Section 17-9). If the voltage on the capacitor is to be 850 V, what is the required capacitance?
(d) If this capacitor were to be made from activated carbon (Section 17-7), the voltage would be limited to no more than 10 V. In this case, how many grams of activated carbon would be required?
(e) Is this practical?
