Explanation:

For the first question, when the bus moves east, relative to the moving - east passenger, the stationary man on the curb appears to move west at the bus's speed due to relative motion. For the second question, a coordinate system is used to define positions and measure motion, serving as a frame of reference.

Answer:

Question 9: move west at a speed that is equal to the bus's speed.
Question 10: coordinate system
