Chapter 9: Q. 30 (page 603)

In Problem, the vector v has initial point P and terminal point Q. Write v in the form ai + bj; that is, find its position vector.

Short Answer

Expert verified

v=9,3Positionvector9i+3j

Step by step solution

01

Step1. Given Information

Initial point P-3,2

Terminal point Q6,5

We know that if Px1,y1is the initial point and Qx2,y2is the terminal point then the position vector is

v=x2-x1,y2-y1

02

Step 2. Calculating the position vector 

v=x2-x1,y2-y1

for P (-3,2)

and Q (6,5)

v=6--3,5-2v=9,3

in vector form v=9i+3j
