The _______ of two or more vectors is the sum of the vectors.

• components
• scalar
• resultant
• magnitude

If a boomerang is thrown 20 m in a straight line and returns exactly to the spot it was thrown what is its displacement?

• 20m
• 40m
• 0m
• -20m

What is the total displacement?
100 m/s        230 m/s
<------        --------->

• 30 m/s to the right
• 230 m/s to the right
• 130 m/s to the right
• This is a balanced force

In practice A of the figure, what is the direction of the resultant displacement?

• 63 degrees, South of East
• 63 degrees, North of West
• 27 degrees, North of West
• 27 degrees, South of West

Find the length of the missing side. 

• 17 cm
• 22 cm
• 15 cm
• 13 cm

In practice B of the figure, which displacement is the vertical component? 

• 40 km, South
• 40 km, North
• 30 km, East
• 30 km, West
