Find the magnitude of the sum
of these two vectors:
12.0 m
45.0° 9.66 m

me with this

8.57 m

Explanation:

To solve the problem, we have to decompose the two vectors along the two directions first:

Vector A:

- x component: Ax = +9.66 m

- y compoment: Ay = 0 (the vector lies along the x-axis)

Vector B:

- x component:

- y component:

So now we can find the sum of the two vectors by adding the components along each axis:

And the magnitude of the sum is given by Pythagorean theorem:

correct it is c.) b b
