Question 1

• 1.) Suppose you are standing in the aisle of a
  bus that travels along a straight road at
  100km/h, and you hold a pencil still above the
  bus. Then relative to the bus, the velocity of
  the pencil is 0 km/h, and relative to the road ,
  the pencil has a horizontal velocity?
• less than 100km?hr
• 100 km/hr
• more than 100km/hr

Question 2

• 2. Imagine a place in the cosmos far from all
  gravitational and frictional influences. Suppose
  an astronaut in that place throws a rock. The
  rock will
• a) gradually stop.
• b) continue in motion in the same direction at
  constant speed.

Question 3
3. Mac and Tosh are arguing in the cafeteria. Mac
says that if he throws his jello with a greater
speed it will have a greater inertia. Tosh argues
that inertia does not depend upon speed, but
rather upon mass. With whom do you agree? Why?

• 4. If you were in a weightless environment in
  space, would it require a force to set an object
  in motion?

Yes

Question 5

• 5. Mr. Wegley spends most Sunday afternoons at
  rest on the sofa, watching pro football games and
  consuming large quantities of food. What effect
  (if any) does this practice have upon his
  inertia? Explain.

Mr. Wegelys inertia will increase!
