SUMMARY
The discussion centers on calculating the contact force between two blocks on a frictionless tabletop, subjected to an external force, F, resulting in a constant acceleration of a = 2.45 m/s². The confusion arises from the misconception that the contact forces between the blocks are different, which is clarified through the understanding of Newton's Third Law. The contact force exerted by block 1 on block 2 is equal in magnitude and opposite in direction to the force exerted by block 2 on block 1, confirming that there is only one contact force acting between the two blocks.
