• 270T (west)

• 180T (south)

• 090T (east)

A dog runs west at 7.00 m/s and rapidly turns south and runs at 5.00 m/s. What is the dog's resultant velocity of these adjacent vectors?

• 8.60 m/s Southwest
• 12.00 m/s South
• 7.00 m/s West
• 5.00 m/s South

What property of vectors states that vectors can be added in any order?

• Commutative Property
• Associative Property
• Distributive Property
• Transitive Property

Which of the following statements are true of similar triangles?

• the corresponding sides of similar triangles are proportional

• similarity can be determined if you know all the angle measurements of both triangles

• the corresponding angles of right triangles are congruent

• All of these are true of similar triangles.

A dog runs 20.0 m north and then turns to travel 40.0 m west of her starting position. What is the magnitude of her displacement?

• 10.0 m

• 40.0 m
• 44.7 m

• 60.0 m

What is the approximate Cartesian angle of a vector whose component vectors are +3.00 m vertically and -6.00 m horizontally

• 90 degrees

• 63.4 degrees

• 153 degrees

• 45.0 degrees

Can a vector's magnitude be negative?

• Yes, if moving along the negative axis

• No, positive or negative signs indicate direction, not value of magnitude

How would you resolve the vector R into components R_x and R_y if the length of R is 30.0 m and it's reference angle is 35^o

• Rx = 30 cos(35), Ry = 30 sin(35)
• Rx = 30 sin(35), Ry = 30 cos(35)
• Rx = 30 tan(35), Ry = 30 cot(35)
• Rx = 30 sec(35), Ry = 30 csc(35)
