8. Tom runs away from his house to a friend’s and stays there for a brief time before taking off again
and running to another friend’s house that is further away. He stays there for a long time. Draw a p v. t
graph that would show Tom’s journey (just give me the shape)
9. Draw a p v. t and v v. t for the following situations
a. Standing still
b. Accelerating away
c. Moving back toward your starting point at a constant speed
10. Say you were given the following shape in your graph matching lab. What would you have had to
do to match this shape (in a p v. t graph)
11. A man throws a ball down at 4 m/s. What is the ball’s velocity after 5.1 s?
