Question

What is the magnitude of a vector with components (15 m, 8 m)?

Answer 1

The answer is 17 m because you have to add the 15 m and the 8 m together to get the answer so it will be like this 17x17 = 15x15 + 8x8 got it?

Answer 2

The magnitude of a vector with components (15 m , 8 m) is 17 m

Further explanation

Vector is a quantity that has a magnitude and direction.

A vector in a cartesian coordinate is represented by an arrow in which the slope of the arrow shows the direction of the vector and the length of the arrow shows the magnitude of the vector.

A position vector of a point is a vector drawn from the base point of the coordinates O (0,0) to that point.

The addition of two vectors can be done in the following ways:

$\overrightarrow {AB} + \overrightarrow {BC} = \overrightarrow {AC}$

A negative vector is a vector with the same magnitude but in opposite direction.

$\overrightarrow {AB} = -\overrightarrow {BA}$

Let's tackle the problem!

If there is a vector with components x and y, then how to find the size of a vector is as follows:

Magnitude of A Vector = $\large {\boxed {\sqrt{x^2 + y^2}} }$

The magnitude of a vector with components (15 m , 8 m) is :

$\sqrt{15^2 + 8 ^2} = \sqrt{225 + 64} = \sqrt{289} = 17 ~ m$
