Avector has a x component of -25 units and y component of 40 units find the magnitude and direction

47.2 units at

Explanation:

The components of the vector are:

x = -25

y = 40

The two components form the sides of a right triangle, of which the vector itself represents the hypothenuse; therefore, we can find the magnitude of the vector by using the Pythagorean theorem:

Concerning the direction, we can apply the formula:

The x-component is, however, negative, so the correct angle (measured anticlockwise from the positive x-axis) is

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
