The #x# component of a vector is 8.7 units, and its #y# component is 06.5 units. What is the magnitude?
The magnitude of the resultant is
Since one vector is on the x-axis and the other is on the y-axis, we can use a right triangle and the Pythagorean theorem to determine the magnitude of the resultant, which is the hypotenuse.
Take the square root of both sides.
