Question

A vector w has initial point (3,4) and terminal point (5,−1).Write w in the form w=ai+bj.

Answer 1

Solution

Step 1:

Write the Initial and the terminal

Initial point R = 3i + 4j

Terminal point M = 5i - j

Step 2:

W = ai + bj

a = 5 - 3 = 2

b = - 1 - 4 = -5

Final answer

W = 2i - 5j
