Vector a has components ax=9.0m, ay=12.0m, vector b has components bx=16.0m by=12.0 the resultants of vector a and vector b is r=a+b. the magnitude of vector a is?

Hi Devonte11! In order to find the magnitude of a vector, all you need to do is use the Pythagorean theorem.

Let c be the magnitude of Vector A.

c = √(x²+y²); in this case, your ax = x, while your ay = y

substituting the values to the equation gives:
c = √(81+144)
c = 15.099 or ≈ 15
