One 2.0kg paint bucket is hanging by a massless cord from another 2.0 kg bucket, also hanging by a massless cord.
a) If the buckets are at rest, what is the tension of each cord?
b) If the two buckets are pulled upward with an acceleration of 1.30m/s2 by the upper cord, calculate the tension in each cord.

Don't know where to start :(
