It may appear at first glance that Newton's 2nd and 3rd laws are independent claims. This, however, is not true - Newton's 3rd law is simply a consequence of Newton's 2nd law. In this problem, you will prove Newton's 3rd law for the normal contact force between two objects, using only Newton's 2nd law. Consider two blocks with masses my and m₂ in contact, with external forces F₁ and F₂ applied, as shown in the figure. The free body diagram for each block is also given, with internal forces fa and fo. as shown. F₁ F₂ F₁ m₁ m₂ m₁ fa fb m₂ F₂ Complete the equations of motion for the entire system, as well as blocks 1 and 2 individually. Note, the forces have a signed magnitude, where positive values correspond to the positive x-direction
