What is the acceleration of the 2.0 block in the figure across the frictionless table?
Hint: Think carefully about the acceleration constraint.
I've attached the diagram.
The Attempt at a Solution
For block A: mAa1=2T
For block B: mBa2=T-Fg
and no forces in x direction
So I assume the tension is equal because it is the same string. I also assume that the accelerations are different for the blocks though I'm not completely sure what to assume/why. All I really need is an explanation as to what I should know about the acceleration and why that is.
