*sigh*

If the two bodies are side-by-side, then pushing on one pushes on the other, too. The force you apply to one body gets applied directly to the other, same magnitude, same direction. Weight is not involved.

learningphysics,

That's very true. I have the feeling the two blocks are actually side-by-side. If I were harhar, I would be yelling at the teacher by now for writing such an incomprehensible problem.

But Warren, this isn't true. The force acting on the second mass isn't equal to the force being applied to the first.

The accelerations of the two masses are the same.
