What is the displacement from 2 to 10 seconds?

• 64 km
• 100 m
• 64m 
• 32 m 

What are the components of this vector?

• South and East
• South and West
• North and East
• North and West

What is the resultant of these two vectors?

A boat is traveling at 50 m/s in a river flowing at 15 m/s in the exact same direction. What is the resultant velocity of the boat?

• 65 m/s

• 35 m/s

• 52 m/s

• It cannot be determined

A hiker walks 40 m due North then turns due South and walks 60 m. What is the resultant displacement?

• 100 m North

• 100 m South

• 20 m North

• 20 m South

When finding the resultant of two vectors quantities, you must place them

• tip to tail

• tip to tip

• tail to tail

• So they make a triange
