A new electric car makes use of storage batteries as it source of energy. Its mass is 1300kg and it is powered 26 batteries, each 12v, 52 A-h. Assume that the car is driven on the level at an average speed of 40 km/h, and the average friction force is 240N. Assume 100% efficiency and neglect energy used for acceleration. Note that no energy is consumed when the vehicle is stopped since the engine does not need to idle.a. determine the horsepower requiredb.after approximately how many kilometers the battery must be changed?
