A vector quantity has ______________.
Magnitude only
Magnitude and Direction
Direction only
Direction and angles
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
Tony walks 3 m and then 4 m. Which of these can not be his displacement?
7 m if they are in the same direction
1 m if they are in opposite directions
5 m if they are perpendicular directions
8 m if they are in the same direction
Which of the following represents the y-axis (vertical) component of Vector “V” shown in the figure?
10 m/s, North
10 m/s, South
12 m/s East
12 m/s West
Which is the best description for the 2 vectors pictured?
AB represents 20 m Southeast and CD represents 10 m Northwest
AB represents 10 m Southeast and CD represents 20 m Northwest
AB represents 10 m Northwest and CD represents 20 m Southeast
AB represents 20 m Northwest and CD represents 10 m Southeast

For projectiles, ax = __________ and ay = __________.
0 m/s/s and -10 m/s/s
-10 m/s/s and 0 m/s/s
0 m/s/s and 0 m/s/s
-10 m/s/s and -10 m/s/s
Which will hit the ground first?
A because it is higher
A because it is moving faster
B because it is lower
B because it is moving slower
Which will hit the ground first if dropped at the same time?
The blue ball because it doesn't have to go as far.
The blue ball because it falls straight down.
The green ball because gravity accelerates it.
Both will hit the ground at the same time.
A box is dropped from an airplane. Neglecting air resistance, where will the box be in relation to the plane when the box hits the ground?
directly under the plane because it has the same Vx as the plane.
behind the plane because the box will drop straight down
in front of the plane because the plane will throw it forward
there is not enough information to tell
Which graph best represents the ball's horizontal velocity as it travels as a projectile?
Click all the measurements needed to determine the range of a horizontal projectile.
height
horizontal velocity
mass of the projectile
What is the best angle to launch a projectile to reach maximum range?
10o
30o
45o
60o
