Homework Help: Tension in the string

  1. Oct 20, 2008 #1
    1. The problem statement, all variables and given/known data
    A 2.00 kg object placed on a frictionless, horizontal table is connected to a string that passes over a pulley and then is fastened to a hanging 8.00 kg object, as shown in the figure. Find the magnitude of the acceleration of the two objects and the tension in the string.

    3. The attempt at a solution
    Through calculation, I know both objects are accelerating at 7.84 m/s2. Since the surface is frictionless, I assume the tension is contributed by the 8kg object accelerating downward and gravitational force. so T= 8 x (9.8+7.84) = 141.12N. Is my answer correct?
