chapter 5 problem solving exercises
  • 16 - for a 30-60-90 triangle the vertical would be 1/2 and the horizontal would be sqrt(3)/2
  • A-1 vectors
  • A-2
  • A-7 vectors
  • A-9
  • A-10    7 m is close to 23 ft, she skied off a cliff not a "bump"

problem solving exercises free fall  problems B3, B4

If you want to hear the story about Annie Edson Taylor click here: going over the falls
This is a Radiolab excerpt, it starts with a story about cats but eventually gets to Annie.

I recommend you search the Radiolab library and listen to a few other shows. This is one of the best science based radio programs ever produced: educational, entertaining, and captivating.

Chapter 2 test Wednesday
chapter 2 review

  • read page numbers 7 and 8 (review, read carefully)
  • on page numbers 9-11 do problems 3-13, 15-18, 20, 22-29
  • on page number 12 do problems 1, 2

vector worksheet #3

  • problem 1, the bag of marbles weighs 101N (1 N per marble)
  • problem 5 has an error. Treat the 15m/s similar to problem 2, meaning it is the vertical vector, the vector which in problem 2 represented the weight. The vectors you would solve for are the vector down the ramp and the vector into the ramp (same as problem 2).
