1. The problem statement, all variables and given/known data Blocks with masses of 1 kg, 2 kg, and 3 kg are lined up in a row on a frictionless table. All three are pushed forward by a 12 N force applied to the 1 kg block. How much force does the 2 kg block exert on the 3 kg block? How much force does the 2 kg block exert on the 1 kg block? 2. Relevant equations Newtons third law F=m(a) ? 3. The attempt at a solution This isn't my first time posting on this forum and I know that I really should include at least an attempt at the solution but what I'm asking for is just a general quick idea to help me get moving along, as I am stuck. Thank you very much.
