This is hard to explain without having a picture, but there is a 1 kg hanging off the table. And a string is connected from that to a 10kg weight. From that weight on the other side, a 5kg weight hangs off the table. They system is moving to the left at 2 m/s. Do I have to compensate for that in any of my calculations because I believe it accelerates to the right b/c of the larger weight.
