1. The problem statement, all variables and given/known data The three blocks are attached via a massless, frictionless pulley system, as shown. The frictionless plane is inclined at an angle = 60 degrees. When released from rest, the 20kg block will start to slide down the plane. Find the tension in the string. The image is attached. 2. Relevant equations Fnet = ma 3. The attempt at a solution For the 20 kg block I got, ma = mgsinθ - T 2kg block- ma = 2T - mg 3kg block: ma = 2T - mg The only problem is that the acceleration of all of the masses is different. How do I find the acceleration of each? Is it a ratio of the tensions, but then the 2kg and 3kg would have the same acceleration which wouldn't make sense?
