    I need to just know how to do it, not the answer. :)

    Looks likes its an energy problem, so you will need to use your law of conservation of energy equations. Can you identify the 3 forces acting on the sled? For the second part of the problem, what do you think the value of the final velocity is when it reaches its highest height as stated in the problem?
