Find the displacement for a hiker who walks 3.50 km north, and then turns around and walks 3.00 km south.

• 0.50 km [S]
• 0.50 km [N]
• 6.50 km [S]
• 6.50 km [N]

At an airport an aircraft moves from the terminal building to the end of the runway.

• A
• B
• C
• D
• E

Answer explanation

The plane travels 200 m east, then 50 m south, then 200 m west, and 250 m south.

You add it all up for distance. 200+50+200+250 = 800

For displacement, you have to consider the the directions. So for the South direction (250+150 = 400) and for the East/West direction (200-200 = 0). The displacement of the plane from where it started is 400 m south.

Hence the answer is D.

Jermaine runs exactly 2 laps around a 400 meter track. What is the displacement?

• 800 m
