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 1 12 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 1 A on 1 2 on 1 1 x FF F m a =−= ( ) on 2 1on 2 3 on 2 2 x F m a ( ) on 3 2 on 3 3 x m a == Adding these three equations and using Newton’s third law
