Given that one object is 78 kg and the other is 103 kg; the two objects are in contact and at rest on a horizontal surface; a 733 N force is exerted on the 78 kg object.... I know the formula is F of mass 2 on mass 1 = F - force of friction - ma, but I can't find the force of friction.... can someone show me the light?

The two objects are touching; the 78 kg object is pushed by a 733 N force.

The acceleration is 2.58 m/s^2.

your question is not clear. describe positions of the objects.

maybe this'll help.... if a force on body one pushes on body two....you now have friction of one AND two. You have only the original force pushing on: One and twos friction AND mass.
