Question

Write the resultant if the 2 vectors as an ordered pair.

<5, -2> and <0,0>

Answer 1

To find the resultant vector, you need to base the solution from the Pythagorean Theorem.

Step 1. Find z1 by adding x1^2 and y1^2.
z1= 5^2 + 0^2 = 5

Step 2. Find z2 by adding x2^2 and y2^2.
z2= -2^2 + 0^2 = 2

Step 3. Find c.
5^2 + 2^2 = c^2
c=square root of 29
c=5.39

The final answer is 5.39.
