7.10.Model:The blocks are to be modeled as particles and denoted as 1, 2, and 3. The surface is frictionless and along with the earth it is a part of the environment. The three blocks are our three systems of interest. Visualize:The force applied on block 1 is A on 112 N.F=The acceleration for all the blocks is the same and is denoted by a. Solve: (a)Newton’s second law for the three blocks along the x-direction is ()on 1A on 12 on 11xFFFma=−=∑( )on 21on 23 on 22xFma∑( )on 32 on 33xma==∑Adding these three equations and using Newton’s third law
