1. The problem statement, all variables and given/known data blocks with masses of 1kg,2kg,3kg are lined up touching on a frictionless table. All three are pushed by a 12N force being applied to block 1(1kg). how much force does the 2kg block exert on a) the 3kg block? b) the 1kg block? 2. Relevant equations[/b F=MA 3. The attempt at a solution A=F/M = A=12N/1kg= an acceleration of 12. for the 1kg block.
