Question

A dog searching for a bone walks 3.50 m south, then 8.20 m at an angle of 30.0 degrees north of east, and finally 15.0 m west. Use graphical techniques to find the dog's resultant displacement vector.

Answer 1

grab a piece of graph paper and draw each vector to scale, each one starting at the head of the last one. Draw the single vector that gets you from the start to the finish and find its magnitude and direction.
