(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data - In this problem, "m" slides down "M" (that is inclined at angle alpha) to the point "P" at the bottom-right of the triangle. "m" starts with zero velocity and "M" starts with zero velocity. There is zero friction between "m" and "M". There is also zero friction between "M" and the surface that it rests on (not shown in picture). So the questio is what is the velocity of "m" when it reaches the "P"? I don't even know how to approach this problem, so I dont have any work done, but my teacher told me that I would have to use the conservation of linear momentum and mechanical energy. Thanks for all the help.

2. Relevant equations - Emech = delta k + delta u; p = m1v1f + m2v2f = 0

3. The attempt at a solution - my teacher mentioned the relavent equations. but i really dont know how to even start this problem. i only know that for the free body diagram of "m" that theres sumFy = n-mgcosalpha; mgsinalpha to the right and for "M" umFy = n-mg; i know for sure that the free body for "M" is missing forces from the "m" but im not sure how to account for that
