Jane and John, with masses of 54kg and 63kg , respectively, stand on a frictionless surface 11m apart. John pulls on a rope that connects him to Jane, giving Jane an acceleration of 0.82m/s2 toward him.
Part A
What is the magnitude of the John's acceleration?

the force is the same on each end of the rope.
forcejohn=forcejane
massjohn*ajohn=massjane*ajane
find ajohn
