    physics question

    Enter text here.A car accelerates at 0 60 mph in 3.7 seconds. Equiped with motor (up to 14000 rpm) produces 288 hp (215kW). The battery cells are combined in 11 blocks, providing 34 V each, connected in series circuit. How much current is drawn from the battery at maximum power?

    i didnt pay attention in class. someone help me :P

    Max. power of a battery=215000W
    Total voltage= 34*11=374
    Power=Voltage*Current
    215000/373=574.9A
