Q1:

An object moves left at a constant speed of 5 m/s for 3 s. How far does the object move to the left?

Q2:

An object moves north at 12 m/s for 10 seconds and then stops and stays motionless for 10 seconds before moving north at 12 m/s for another 10 seconds. What is the object’s average northward velocity?

Q3:

An object moves forward at 10 m/s for 4 s and then moves backward for 2 s at the same speed. What net forward distance does the object move from its starting position?

Q4:

What is the average westward velocity of an object that moves 11 m to the west in a time of 0.25 s?

Q5:

What is the average eastward velocity of an object that moves 6 m east and 2 m west in a total time of 0.75 s? Answer to one decimal place.

Q6:

What is the total time for which the cyclist moves?

What is the cyclist’s average velocity to the east from when he joins the road to when he dismounts? Give your answer to two decimal places.

Q7:

An object is initially at rest and then moves 100 m to the left and then 40 m to the right. The time taken between the object first starting to move and having moved 40 m to the right is 20 seconds. What is the object’s average velocity to the left for the 20 s after it begins moving?

Q8:

How much time passes between the person first leaving his house and arriving at his appointment?

What is the distance between the person’s house and their office?

What is the person’s average velocity between first leaving his home and finally arriving at the office? Give your answer to two decimal places.

Q9:

What was the total distance the ball moved?

What was the ball’s net displacement toward the wall?

How much time did the ball move for? Give your answer to two decimal places.

What was the ball’s average speed during its motion, to the nearest meter per second?

What was the ball’s average velocity toward the wall from when the ball was kicked to when it rolled back from the wall and came to a stop? Give your answer to two decimal places.

Q10:

The change of an object’s displacement with time is shown in the displacement–time graph. In which region of the graph is the speed of the object decreasing?

Q11:

What is the drone’s net displacement from the start of its motion to the end of its motion?

How fast does the drone move eastward in the second part of its travel?

How fast does the drone move westward in the last part of its travel? Round your answer to two decimal places.

How fast does the drone move southward in the last part of its travel? Round your answer to two decimal places.

Q12:

What is the person’s displacement from their starting point after 2 seconds?

What is the person’s displacement from their starting point after 3 seconds?

What is the person’s displacement from their starting point after 4 seconds?

What is the person’s displacement from their starting point after 5 seconds?

Q13:

What is the displacement of the fish from its starting point 12 s after it starts moving?

For how long does the fish swim to the left?

What is the fish’s average velocity while it moves to the right? Answer to one decimal place.

What is the average velocity of the fish over the 12 s that the fish moves for?

Q14:

What total distance did the ball move?

What was the ball’s net displacement toward the wall?

How much time did the ball move for? Give your answer to two decimal places.

What was the ball’s average speed during its motion to the nearest meter per second?

What was the ball’s average velocity toward the wall from when the ball was kicked to when it had rolled back from the wall and come to a stop? Give your answer to two decimal places.
