The new EV-1 electric car makes use of storage batteries as its source of energy. Its mass is 1580 kg and it is powered by 29 batteries, each 12 V and 54 A-h. Assume that the car is driven on the level at an average speed of 44.4 km/h, and the average retarding force is 240 N. Assume 100% efficiency and neglect energy used for acceleration. Note that no energy is consumed when the vehicle is stopped since the engine doesn't need to idle.
a) Determine the horsepower required for the motor.
P =
b) After approximately how many kilometers must the batteries be recharged?
