Vector A has a magnitude of 6.0 m and points 30° north of east. Vector B has a magnitude of 4.0 m and points 30° west of south. The resultant vector A+ B is given by

The resultant vector is given by .

Explanation:

Let and , both measured in meters. The resultant vector is calculated by sum of components. That is:

(Eq. 1)

The resultant vector is given by .

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
