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.

Hi bob123ed. http://img96.imageshack.us/img96/5725/red5e5etimes5e5e45e5e25.gif [Broken]

Does the textbook give the answers?

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.
