How do i find tension on cord

    how do i find tension on cord C before one mass hits the ground?

    i got the acceleration =(3.2-1.2/3.2+1.2)9.8 = 4.6
    now is the tension sum of their masses times acceleration?

    Re: Tension

    Yes, but what is that?

    Isn't it the difference in their weight that you used to calculate the acceleration in the first place?
