1. The problem statement, all variables and given/known data Find the acceleration of the system The rope is massless The mobile pulley is not massless, it weighs 20 grams. Find the accelereation of the system 2. Relevant equations F=mg F=ma g = 9.8 3. The attempt at a solution for W1: Fy = 2T-W1 = ma 2T-(500+20)*g = (500+20)*a 2T-520g = 520a (equation 1) for W2: Fy = W2-T=ma 300g-T=300a T = 300(g-a) (equation 2) equation 2 in equation 1 gives a = 1,43 Is it correct?
