ALright i seem to be a little stuck on a Homework problem. Basicly there is a downward curving slope that level so for a few meters> throuhgout a good chunk of the problem the track is frictionless. And the end the coeff of kenetic friction is .50. They want to know how far the complelty inelastic system travels. For the problem set up there is a block of mass M1 sliding down the slide. At the bottem there is another block of Mass 2.00M1. This is all the information i'm given.
