Tension and Acceleration

  1. Jun 21, 2009 #1
    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?

    That's correct.
