Explain. O The vectors are orthogonal because u . v = 0. O The vectors are orthogonal because cos 0 = -1. O The vectors are parallel because u . v = 0. O The vectors are parallel because cos 0 = -1.An object experiences two velocity vectors In its environment. What Is the true speed and direction of the object?
