POSTED MARCH 7, 2008

Here are MY solutions to the extra practice problems (correct to the best of my knowledge).

  1. SEE CLASS NOTES
  2. SEE CLASS NOTES
  3. Free Body Diagram
  4. uk = 0.32
  5. a) FG = 5.9 N
    b) g = 1.4 N/kg
  6. a) a = 5.2 m/s2 [E]
    b) d = 42 m
    c) v = 21 m/s
    d) 3.6 s

HINT: Make sure you look over the textbook section on FUNDAMENTAL FORCES

  • What are the four fundamental forces?
  • Describe each of the forces.
  • Which is the strongest?

Notice...

For those who saw the original "feature" here, I am sad to say it has been removed. I decided that it was, perhaps, not of best interest. If this is either of the Jons showing off this page during their Communications class, I apologize for the disappointment. However, please show the person over your shoulder the "feature" anyways. Its funny.
