How Do You Calculate Acceleration in a Two-Mass System with Newton's Laws?

[dorkee]

Homework Statement

A 10.0-kg mass on a frictionless table is accelerated by a 5.0-kg mass hanging from a table. Calculate the acceleration of the mass on the table. (It gives a picture but I can draw it if nobody can picture the diagram).

Homework Equations

F=ma
F=mg

The Attempt at a Solution

Okay, so I don't even know if I'm going in the right direction but I did this so far:
I solved for the force for the 5.0 kg block which is the one hanging from the table.
F=ma
F = (5.0 kg)(9.8 m/s^2)
F = 49 N

And now I'm just stuck.

Draw a free body diagram of each block and find the net forces acting on them.
