1. The problem statement, all variables and given/known dat
A car travels 20 mi at 60 degrees north of west, then 35 mi at 45 degrees north of east.
Express each displacement vector in unit vector notation. Take the +x-axis due east and the +y-axis due north. Use the component method to obtain the resultant displacement vector in unit vector notation.
[tex]\ A = \ A_x i + \ A_y j[/tex]
[tex]\ B = \ B_x i + \ B_y j[/tex]
[tex]\ C = \ C_x i + \ C_y j[/tex]
A= -20sin60i+35cos60j
B=35cos45i+20sin45
C=?
How do I find C, since no lengths were given. Did I do A and B correctly?
