1. The problem statement, all variables and given/known data Body A weighs 102 N, Body B weighs 32 N. The coefficeints of friction between A and the incline are .56 for static, .25 for kinetic. Angle is 40 degrees. Find the acceleration of the system when block A is at rest... when it is moving up the incline, and when it is moving down the incline. (Block A is on the ramp attached to a string that goes up to the top of the ramp, down a pulley that attaches block B) 2. Relevant equations Fnet=MA Ff=Fnormal(coefficient of friction) Fnet=T-Ff Fnormal=Mgy 3. The attempt at a solution I have done problems just the same as this very recently, but for some reason, I cannot think of how to get the tension in the string/rope. I dont know why, but it just seems to be escaping me, and after getting T, the rest of the problem is already solved. I have the friction, equal to mgy multiped by the coefficient. So the acceleration would be the T-friction, all divided by the mass of the system.
