An automobile having a mass of 1700 kg (chevy volt with one person) is traveling at 15 m/s. on average, it gets an "electric mileage" of 300 wh/km and the battery-to-wheel efficiency is 90%. a. what is its kinetic energy in kj? how much work must be done to bring it to a stop?
b. assume the vehicle is able to recapture half of the kinetic energy through a generator into the battery, and that this happens 50 times over 100 km of driving. how much further was the car able to travel because of regenerative braking?
