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

    Homework Statement A rollercoaster cart mass = 55kg velocity = 5m/s height = 5m what is the total energy that the cart has at this position? Homework Equations would s=d/t be relevant? The Attempt at a Solution already calculated gravitational potential energy: GPE = m*g*h =...
