An electric car is designed to run on a bank of batteries with a total potential difference of 23 V and a total energy storage of 1.8×107 J. If the electric motor draws 7.0 kW, what is the current delivered to the motor? Answer in units of A. 012 (part 2 of 2) If the electric motor draws 7.0 kW as the car moves at a steady speed of 24.0 m/s, how far will the car travel before it is “out of juice"? Answer in units of m.
