Calculate Displacement and Distance

A hiker travels 1.0 kilometer south, turns and travels 3.0 kilometers west, and then turns and travels 3.0 kilometers north. What is the total distance traveled by the hiker?

• 3.2 km

• 3.6 km

• 5.0 km

• 7.0 km

A cart travels 4.00 meters east and then 4.00 meters north. Determine the magnitude of the cart’s resultant displacement

• 16.0 m

• 2.83 m

• 5.66 m

• 8.00 m

A person walks 150. meters due east and then walks 30. meters due west. The entire trip takes the person 10. minutes. Determine the magnitude and the direction of the person’s total displacement

• 180 m

• 153 m

• 120 m East

• 180 m West

Which is a vector quantity?

• speed

• work

• mass

• displacement

A child walks 5.0 meters north, then 4.0 meters east, and finally 2.0 meters south. What is the magnitude of the resultant displacement of the child after the entire walk?

• 1.0 m

• 5.0 m

• 3.0 m

• 11.0 m

What is a frame of reference?

• relative motion
• the length between two points
• objects that are not moving
• vectors that describe motion

Are people on a plane moving?

• Yes, planes are designed to transport people.
• No, you sit still on plane.
• It depends on what you compare it to.
• Flight is a myth.  The Earth is flat.

Because displacement has a magnitude and direction it is called a ______. 

• distance
• vector
• arrow
• length

When two displacements are in a straight line you can...

• use the pythagorean theorem
• resultant vector
• add their directions
• add their magnitudes

When two displacements are not in a straight line you can...

• use the pythagorean theorem
• resultant vector
• add their directions
• add their magnitudes
