Question
A women walks 250m in the diretuibn 30 degrees east of north, then 175m east.
a)what is the magnitude and angel of her final displacement from the starting point?
I should be getting 370m and 36 degrees north of east but I keep on getting the wrong answers.
East: 250Sin30 + 175
North: 240cos30

All angles are measured CCW from +x-axis.
Disp. = 250m[60o] + 175m[0o].
Disp. = (250*Cos60+i250*sin60) + 175.
Disp. = 125+216.5i + 175 = 300 + 216.5i = 370m[36o].
Disp. = 250m[60o] + 175m[0o].
Disp. = (250*Cos60+i250*sin60) + 175.
Disp. = 125+216.5i + 175 = 300 + 216.5i = 370m[36o].
