Battery Energy and Altitude Change

  1. Oct 29, 2008 #1
    1. The problem statement, all variables and given/known data

    An electric scooter has a battery capable of supplying 120 Wh of energy. If friction forces and other losses acount for 60.0% of energy usage, what altitude change can a rider achieve when driving in hilly terrain, if the rider and scooter have a combined weight of 890N.

    2. Relevant equations

    Not sure...

    3. The attempt at a solution

    I just don't understand...

    Any equations or anything that may make it clear to me would be appreciated. I am capable of solving it for myself, so it is not necessary to actually do the problem. Thank you!
