A drunken sailor stumbles 600 meters north, 550 meters northeast, then 500 meters northwest. What is the total displacement and the angle of the displacement?

Respuesta :

We will make a graph to better understand the displacement of the individual. From the trigonometric properties we will find the required distances.

[tex]d_1 = \frac{450}{\sqrt{2}} = 318.198[/tex]

[tex]d_2 = \frac{400}{\sqrt{2}} = 282.843[/tex]

[tex]D = 500+d_1+d_2 = 1101.041[/tex]

Displacement ,

[tex]x = \sqrt{1101.041^2+(318.198-282.843)^2}}[/tex]

[tex]x = 1101.608m[/tex]

The angle would be

[tex]\theta = cos^{-1} (\frac{1101.041}{1101.608})[/tex]

[tex]\theta = E 1.838\° N[/tex]

Therefore the displacement was of 1101.608m to a angle of 1.838° from East to North.
