Vector & Scalar Quantities  Questions I.2.1
 Give two examples of a scalar and a vector quantity.
 What is a vector? What does it represent?
 What is a resultant vector?
 List the points required for a good vector diagram.
 Are all equivalent vectors also collinear vectors? Explain.
 Graphically add the following vectors.
 26 cm [N 13° E and 50 cm [S]
 12 km [S 46° W] and 22 km [S 80° E]
 250 cm [N], 300 cm [N 47° E] and 7 m [S 13° W]
 Determine the xcomponent for the following vectors.
 220 m [N 15° W]
 26 km [S 57° W]
 9 m [S]
 55 cm [N 26° E]
 Determine the ycomponent for the following vectors.
 45 m [N 29° E]
 5 km [S 7° E]
 229 cm [N]
 50 cm [W]
 Determine the resultant vector for each of the following using the vector component method.
 7 m [N 57° E] and 15 m [N 75° W]
 88 cm [S 15° W] and 50 cm [N 52° E]
 220 km [S], 102 km [N 13° W] and 71 km [S 8° E]
 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.
