1. The problem statement, all variables and given/known data There is a string hanging down with a 2 kg block attached, at the bottom of this block is another string attached holding another 2 kg block. This has begun to accelerate. The given time is .7 s for acceleration, and the given velocity it reaches is .35. I have to find the tensions of both the strings, and I am not exactly how to/what formulas to use. So far I have calculated the acceleration to = .5 m/s2 though. But I do not know how to use it.
