Did I do this correctly?

Question

A force is given by the vector <75,100>N

Calculate the magnitude and direction of the force vector.

i did...

square root (75^2 + 100^2) = 125 newtons

and...

inverse tangent (100 / 75) = 53.1 degrees

is this correct? if not tell me what i did wrong. thanx.

Answer 1

I get the same. So, brilliant minds think alike.

Answer 2

I agree:

magnitude=sqr((75^2) + (100^2)) = 125 N

angle = atan(100 / 75) * 180) / 3.14159 = 53.13 degrees

Answer 3

Looks good to me.
