Each of 108 identical blocks sitting on a frictionless surface is connected to the next block by a massless string. The first block is pulled with a force of 108N.

Question

Each of 108 identical blocks sitting on a frictionless surface is connected to the next block by a massless string. The first block is pulled with a force of 108N.   
Part A. What is the tension in the string connecting block 108 to block 107? 
Part B. What is the tension in the string connecting block 54 to block 55?

well, if the blocks are moving, then a= F/Masstotal=1/eachmass tension=ma= 107*eachmass*1/eachmass=107N b.tension= massbehind*a= 54N
