2. Add the following vectors in order “Tip-to-Tail”B
Resultant C
A + B + C= Resultant B
How about B + C + A = Resultant C D

3. Be sure to draw Arrows and not just lines
Resultant C B B
Resultant C D C D
Try this one: B + D + C= Resultant

4. 90 0
180
270

5. 90
Using your best estimate, label 3 different ways to state the direction of this vector. 0
180
270

6. What is the total distance traveled by the hiker?
After walking 11 km due East from camp, a hiker then walks 11 km due North.
What is the total distance traveled by the hiker?
Determine the total Displacement from the reference point (camp)
11 km
R2 = x2 + y2
Total Dist = 22 km
15.56 m/s
Ө= Tan-1(o/a)
Displacement = ?
Ө = 45º
11 km Ө
Recall Pythagorean Thm.

7. What is the magnitude and direction of the Net Force (Resultant)?
Two children push on a toy box at the same time. One pushes with a force of 125 N West and the other pushes 165 N South.
What is the magnitude and direction of the Net Force (Resultant)?
R2 = x2 + y2
125 N
165 N Ө
Ө= Tan-1(o/a)
207 N
Ө = 52.8º S of W
Recall Pythagorean Thm.

8. What is the magnitude and direction of the plane’s resultant velocity?
While flying due West at 120 km/hr, an airplane is also affected by a 45 km/hr wind blowing due North.
What is the magnitude and direction of the plane’s resultant velocity?
R2 = x2 + y2
Ө= Tan-1(o/a)
128 km/hr
45 km/hr Ө
Ө = 20.6º N of W
120 km/hr

10. A Motorboat heads due East at 16 m/s straight across a river
A Motorboat heads due East at 16 m/s straight across a river. The river flows due South at 9.0 m/s
What is the magnitude and direction of the boat’s resultant velocity? (relative to the shore)
R2 = x2 + y2
Ө= Tan-1(o/a)
