Homework Help: Finding total energy from the top of a hill on a rollercoster?

  1. May 30, 2010 #1
    1. The problem statement, all variables and given/known data
    A rollercoaster cart
    mass = 55kg
    velocity = 5m/s
    height = 5m
    what is the total energy that the cart has at this position?

    2. Relevant equations

    would s=d/t be relevant?

    3. The attempt at a solution
    already calculated
    gravitational potential energy: GPE = m*g*h = 2695
    kinetic energy: KE = 1/2*m*v^2 = 687.5

    You have potential (gravitational, if you will) energy, kinetic energy. I suppose you are not expected to calculate anything more.
