1. The problem statement, all variables and given/known data Cart is on an inclined plain, attached to the cart is a weightless string going to a pulley attached to another mass. There is no friction. Cart Weight: 0.5Kg Mass Weight: 0.1Kg Plain Angle: 20 Degrees Diagram: See below Question: Determine Tension in string and acceleration. 2. Relevant equations Fg=ma 3. The attempt at a solution http://img254.imageshack.us/img254/6286/physji3.jpg [Broken] With the two equations I then made them both equal 5a and then used elimination, I got T=0.6582N and a=3.21m/s. I kinda doubt this is the right answer.
