2. A vector has equal, positive x and y components and zero z component. what is the angle between this vector and the x axis?
3. A vector A has an x component Ax=3 and a y component Ay= -1. what are the x and y components of the vector 2A ? The vector -4A ?
4. What is the magnitude of the vector i + j ?
5. A large oil tanker proceeds from Ivory coast to Morocco via the main port in one city(point A). A small oil tanker proceeds from Ivory Coast to Morocco via its secondary port in different city(POINT B). Are the displacement vectors of the two tankers equal? Are the distances covered equal ?
6. An airplane flies from Freetown to Monrovia and back to Freetown. Is the displacement zero in the reference frame of the earth? In the reference frame of the sun ?
7. Does a vector of zero magnitude have a direction? Does it matter ?
