Is the time measured from the time the weights are released? If so, you know that the acceleration rate is .35/0.7 = 0.5 m/s^2.
For which rope do you want to know the tension? They will be different.
Writing the free body F = ma equation for both weights will let go solve for the tension in both ropes.
So to describe the picture:
There is a rope holding up a 2kg block, this 2kg block has a rope attached to it holding another 2 kg block.
This rope is accelerating. How can I find the tension in the rope?
Time is .7 and Velocity is .35.
I'm really confused.

Yes the time is when it begins accelerating. And we have to find the tensions for both ropes...which is where I'm confused. I was able to find acceleration but now I am not sure how to use it to find the tensions.
