I'm having trouble with this question. ive gotten it wrong 3 times.
Suppose two boxes on a frictionless table are connected by a heavy cord of mass 1.0 kg. Calculate the acceleration (magnitude) of each box and the tension (magnitude) at each end of the cored, using the free-body diagrams shown in Figure 4-53. Assume FP = 42.0 N, ma = 9.0 kg, and mb = 13.5 kg, and ignore sagging of the cord. Compare your results to Example 4-12 and Figure 4-22.

i need to find:
mA acceleration in m/s2
mB acceleration in m/s 2
FTA in Newtons
FTB in Newtons

here are the images they give me:
