Homework Help: Total displacement using vector diagram

  1. Dec 16, 2016 #1
    PF.jpg PF2.jpg A car is driven eastward for a distance of 50 miles, then northward for 30 miles, and then in a direction 30 degree east of north for 25 miles. Draw the vector diagram and determine the total displacement of the car from its starting point.

    The relevant equations I used here are: i) rx= ax + bx + cx
    ii) ry=ay + by + cy
    iii) r= √(rx2 + ry2)
    My attempt regarding this problem is as follows: (Please see the photos)
