PROBLEMS TO BE WRITTEN UP AND TURNED IN AT RECITATION

     This problem is due at your first recitation meeting after Mon. 10/25.
     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 symbols defined in clearly labeled 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. (15 points total)
     
             HRW - CHAPTER 8

        34.  A 4.0 kg mess kit sliding on a frictionless surface explodes
             into two 2.0 kg parts, one moving at 3.0 m/s, due north, and
             the other at 5.0 m/s, 30 degrees north of east.  (a) What is
             the original speed of the mess kit.  (b) How much kinetic
             energy was added to the mess kit by the explosion?
