Motion Review Part 2

• Can two objects have the same speed but different velocities?

Why does an object’s average velocity become zero when it returns to its starting point?

A student walks 30 m east to the library, then 50 m west to the cafeteria. What is the total distance traveled?

• 30 m
• 50 m
• 80 m
• 100 m

A student walks 30 m east to the library, then 50 m west to the cafeteria. What is the displacement?

• 20 m west
• 20 m east
• 50 m east
• 30 m east

A cross-country skier moves from location A to location B to location C to location D. Each leg of the back and-forth motion takes 1 minute to complete; the total time is 3 minutes. (The unit is meters.) What is the distance traveled by the skier during the three minutes of recreation?

A cross-country skier moves from location A to location B to location C to location D. Each leg of the back and-forth motion takes 1 minute to complete; the total time is 3 minutes. (The unit is meters.) What is the average speed of the skier in meters per minute (m/min)? Just provide a numeric answer.
