Homework Help: Momentum Energy Question

  1. Mar 12, 2015 #1
    1. The problem statement, all variables and given/known data
    There is an object with mass m that travels at constant velocity v. Then it starts to travel up a an incline of mass m2 and angle theta.

    Find the velocities of both when the block reaches its highest point and what is this highest point.

    2. Relevant equations

    Energy/momentum equations
    3. The attempt at a solution
    This would be a standard question if it werent for the fact that the incline can move. So I am assuming that the object/incline will be one unit and therefore it'll be like an inelastic collision, but I am not sure.

    No, I do not have an answer for the question.

    Is that the entire question, word for word? Nothing about friction?
    Technically, yes, but sometimes problem setters intend a smooth transition and fail to mention that. Maybe attempt both cases.
