Two blocks are stacked on a frictionless table. A horizontal force F is applied to M2. If M1=1.39kg, M2=3.02 Kg, and F=6.3 N, find the size of the contact force between the two blocks.
If instead an equal but oppositely directed force is applied to M1 rather than M2, find the size of the contact force between the two blocks.
