     Ex: Comprehensive Problem 6.85 (extended)

NEXT TIME
Problems 6.10
         6.15 (for practice only)
         6.20
         6.23 (for practice only)
         6.26 (apply "closed" mechanical energy conservation)
         6.27 (for practice only)
         6.29 (for practice only)
         6.49 (for practice only, "work" is delta(U_spring))
         6.50(a)-(b) 

Read Chs. 6.2 (when is work positive, negative, or zero?)
          6.4 (W_cons vs. W_nc)
          6.8 (units of power vs. units of work or energy)
