Using your best
estimate, label 3
different ways to
state the direction
of this vector.
After walking 11 km due East from
camp, a hiker then walks 11 km
due North.
a)What is the total distance traveled
by the hiker?
b)Determine the total Displacement
from the reference point (camp)
R2 = x2 + y2 15.56 m/s
Ө= Tan-1(o/a)
Ө = 45º
Total Dist = 22 km
11 km
Ө 11 km
Displacement = ?
Recall Pythagorean Thm.
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
Ө
165 N
207 N
Ө= Tan-1(o/a)
Ө = 52.8º S of W
Recall Pythagorean Thm.
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
128 km/hr

Ө
120 km/hr
Ө= Tan-1(o/a)
Ө = 20.6º N of W
A Motorboat heads due
East at 16 m/s straight
across a river. The river
flows due South at 9.0 m/s
a)What is the magnitude and
direction of the boat’s resultant
velocity? (relative to the shore)
R2 = x2 + y2
Ө= Tan-1(o/a)
