Homework Statement



Two blocks are in contact on a frictionless, horizontal tabletop. An external force, F, is applied to block 1, and the two blocks are moving with a constant acceleration a = 2.45 m/s^2.

Homework Equations



what is the contact force between the blocks?

The Attempt at a Solution



I'm a little confused with the question. I see that the force that block 1 exerts on block 2 is different from the one that block 2 exerts in block 1. Does that mean that I have two different contact forces?

In what way are they different? Can you show your reasoning or better yet, your calculation?

I see my mistake. I was somehow mistaking it with static friction.
