Chapter 9: Q. 60 (page 603)

Write the vector v in the form ai + bj, given its magnitude vand the angle 伪it makes with the positive x-axis.

v=3伪=240o

Short Answer

Expert verified

The vector v can be written as 鈭�32i鈭�332j.

Step by step solution

01

Step 1. Given information 

We have been given:

v=3伪=240o

We have to write it in ai+bj form.

02

Step 2. Substitute the values in v=v(cosαi+sinαj).

v=3cos240鈭�i+sin240鈭�jv=3鈰�鈭�12i鈭�32jv=鈭�32i鈭�332j
