Compute each part of given question:
Question: A projected electric vehicle makes use of storage batteries as its source of energy. Its mass is 1560 kg and it is powered by 24 batteries, each 12 V, 95A?h . Assume that the car is driven on level roads at an average speed of 50km/h , and the average friction force is 250N. Assume 100% efficiency and neglect energy used for acceleration. No energy is consumed when the vehicle is stopped, since the engine doesn't need to idle.
Part A: Determine Horsepower required.
Part B: After approximately how many kilometers must the batteries be recharged?
Please help for the above question, totally confused!! Show each steps if possible, Thanks.
