Forces, I want to get the magnitude of the acceleration for the following problem ple

  1. Apr 3, 2012 #1
    Question says.
    Two objects of mass 2kg each are attached to each other by a massless string. One moves vertically and the other is moving on a frictionless surface horizontally and is being pulled the opposite direction by a force of 10 N at 60 degrees to the horizontal get the acceleration of each object and then get tension

    My solution
    Total fy for vertical object is
    T-mg=ma
    For the second I got forces in x direction as 10cos60 -T=ma
    I then solved for a and got a negative answer then I substituted that value to get T. But should I have written a as positive? Is my solution correct

    you give {a} against the point.
    (((One moves vertically))))moves down
    your solution is correct
