- Solve the following using the tail to tip method and the vector component method.
A Great Dane and his owner are enjoying an afternoon of play. The Dane runs 4 km [N 36 E], 6 km [S], 8 km [S 15 W] and finally 10 km [N 72 W] where he lays down and immediately goes to sleep.
- How far and in what direction will the owner have to go to retrieve his dog? (i.e. What is the resultant vector?)
- After examining the tail to tip method and the vector component method of vector addition, state one advantage and one disadvantage for each method.
