1. The problem statement, all variables and given/known data A string is attached to a mass and a pulley at the top end and the mass is free to move and descends with a constant acceleration, a. By applying Newton's Laws to mass m, find an expression for the tension in the string, in terms of m, a and the acceleration due to gravity, g. 2. Relevant equations F=ma 3. The attempt at a solution I was thinking the net force downwards is mg-Tension force. And the net force results acceleration. So ma=mg-tension. is that correct?
