1. The problem statement, all variables and given/known data Three blocks of equal mass (m = 0.88kg) are placed in a row onto a rough ramp (μ=0.77) whose angle of inclination is 35 (degrees). Each block is connected to the other by a massless string. Suppose you pull upwards on the top block with a force of 34.9N. Answer the following: a)Calculate the acceleration of the system. 2. Relevant equations ΣFx 3. The attempt at a solution I have already drawn a free body diagram, co-ordinate plane, and vector diagrams for each of the 3 masses. I also realize that the acceleration of the system holds true for any one of the blocks, that is to say acceleration at m1 equals to acceleration at m2. Furthermore I also realize that all 3 masses are of equal mass. My problem in trying to figure out the acceleration of the system in this case, would be isolating the acceleration ("a"), because there are a lot of tensions to take into account in this question.
