Please help me to solve this problem about
electic potential :

An electric car accelerates for 7.0 s by drawing energy from its 290-V battery pack. During this time, 1200 C of charge pass through the battery pack .
Find the minimum horsepower rating of the car.

  • physics -

    Joules = Watt seconds = i V t = Q t = 1200*290 = 348000 Joules

    Watts = Joules/second = 348000/7 = 49,714 Watts

    I do not remember the conversion from Watts to hp

  • physics -

    do this: Paste in the google search window

    1hp in watts
    then memorize that number

    Then, even lazier, put in the google search window

    49714 watts in hp
