Navigating Cardinal Directions with Vectors

What was the resultant velocity vector R described in the previous lesson?

• 70 mm/s at 60 degrees south of east

• 50 mm/s at 30 degrees north of east

• 65 mm/s at 45 degrees west of north

• 65 mm/s at 41 degrees east of north

What does Mr. P suggest to help with directional impairments?

• Using a larger compass rose

• Rotating the paper frequently

• Ignoring the compass directions

• Drawing a small compass rose and keeping the paper vertical

Why should one not rotate their paper while working with cardinal directions?

• It can lead to confusion in directions

• It makes it easier to draw

• It changes the paper's color

• It can cause paper tears

How is the angle 41 degrees described in terms of cardinal directions?

• 41 degrees west of north

• 41 degrees south of west

• 41 degrees east of north

• 41 degrees north of east

What is the correct description for the angle southward from east?

• East of south

• South of east

• North of east

• West of south

What is the angle described as north of west?

• 180 degrees

• 135 degrees

• 90 degrees

• 45 degrees

What is the equivalent description for 41 degrees east of north?

• 41 degrees west of south

• 49 degrees north of east

• 49 degrees south of east

• 49 degrees north of west

How is 49 degrees north of east related to 41 degrees east of north?

• They are the same

• They are unrelated

• They are complementary

• They are opposite

What are complementary angles?

• Angles that add up to 180 degrees

• Angles that are opposite to each other

• Angles that add up to 90 degrees

• Angles that are similar

What does NE stand for and what is its angle?

• Northwest, 45 degrees

• Northeast, 45 degrees

• Southeast, 45 degrees

• Northeast, 90 degrees
