Chapter 9: Q. 59 (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=14伪=120o

Short Answer

Expert verified

The vector v can be written as -7i+73j.

Step by step solution

01

Step 1. Given information

We have been given:
v=14伪=120o

We have to write it in ai+bj form.

02

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

v=14cos120鈭�i+sin120鈭�jv=14鈰�鈭�12i+32jv=鈭�142i+1432jv=鈭�7i+73j
