PROBLEMS TO BE WRITTEN UP AND TURNED IN AT RECITATION

     This problem is due at your first recitation meeting after MON 2/08.
     It should be written on a single sheet of paper (front and back), or
     if multiple sheets are used, staple them together.  For full credit, 
     the work must be neat, with clearly labeled free-body diagrams.  The 
     labels must be in BOTH words and symbols.  For each part, you MUST 
     briefly explain your strategy in words, as well as neatly showing 
     your physics equations and math, WITH PROPER UNITS at every step. 
     If you do not follow these instructions, DO NOT EXPECT to receive
     anything close to full credit.  (40 points total)
     
     FISHBANE - CHAPTER 4
     24. Refer to this figure.  A horizontal force of magnitude 8.0 N
         pushes on a horizontally-stacked set of blocks on a frictionless
         surface; the masses of the blocks are, from left to right,
         m1 = 2.0 kg, m2 = 3.0 kg, and m3 = 4.0 kg.
         (a) What is the acceleration of the stack?
         (b) What are the forces on block 1, as well as the net force
             on this block?
         (c) Repeat part b for block 2.
         (d) Repeat part b for block 3.
         (e) Repeat part b, but this time with the blocks stacked in 
             reverse order; that is, block 3 becomes the leftmost mass
             and block 1 becomes the rightmost mass.
