Avector points -1.55 units along the x-axis and 3.22 units along the y-axis what is the magnitude of the vector

The magnitude of the vector is 3.57 units.

Explanation:

The x component of the vector,

The y component of the vector is

We need to find the magnitude of the vector. We know that the magnitude of the vector is given by :

So, the magnitude of the vector is 3.57 units. Hence, this is the required solution.

ok

explanation:

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)

neg x, pos y
