displacement are different. Distance is scaler and
displacement is vector. You should know how to
calculate average velocity. You should be familiar
with position- and velocity-time graphs. Velocity can
be calculated from a position-time graph.

4. Jack and Michael are both
running together at constant velocity of 10 m/s.
a. What is Jack's
relative velocity to Michael?
b. What is Michael's
relative velocity to Jack?
5. A rat and a cat are 25 m apart.
When the rat started to run at 2 km/h, the cat
started to chase him at 10 km/h. Can the cat catch
the rat in 10 seconds?
