1. The problem statement, all variables and given/known data Two blocks of wieghts 3.6N and 7.2N are connected by a massless string and slide down a 30 degree inclined plane. The coefficient of kinetic friction b/t the lighter block and the plane is 0.10, that b/t the heavier block and the plane is 0.20. Assuming the lighter block leads, find magnitude of acceleration of the blocks. 2. Relevant equations F=ma Fcos(O)-fk-T=ma 3. The attempt at a solution I dunno, I just guessed at the above equations. Anyway, I'm pretty stuck on this problem (meaning I don't even know where to begin). It's the fact that the question didn't give any forces that threw me off, they just gave masses (and in N too).
