4. 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
Ө= Tan-1(o/a)
Displacement = ?
11 km Ө
Recall Pythagorean Thm.

5. 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)
Recall Pythagorean Thm.

7. 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)
45 km/hr Ө
120 km/hr
