Total displacement = 4.032 km
Displacement is a vector quantity that shows changes in the position of objects in a certain interval of time. Displacement has magnitude and direction
Can be simplified displacement = distanced traveled from starting point to ending point
A hiker walks 53.1 degrees N of E for 2.5 km then due to east for 2 km. compute total displacement
we describe the components according to the x-axis and the y-axis and we find the total displacement of the hiker with the phytagorean formula
x-axis component
2.5 cos 53.1 + 2 km = 3,501 km
y-axis component
2.5 sin 53.1 = 1999
So the total displacement:
[tex]\rm D=\sqrt{1.999^2+3.501^2}\\\\D=\boxed{\bold{4.032~km}}[/tex]
