Efficiency on a roller coaster

  1. Jun 8, 2007 #1
    Hey
    How can i calculate the amount of energy/power required to accelerate my roller coaster on a flat track.
    Mass=4500 approximate when loaded
    Time=2.64secs to reach top speed
    Distance=125m
    Velocity=47.248ms-1
    I know how to calculate it for a track that rises i can use M*G*H/Time
    but my height is 0 so i don't know what to do.
    Thanks Newme
