A fast duck is flying (20i+40j)mi/h at the same altitude as a slow aeroplane flying with a velocity of (-80i+40j)mi/h.How fast and in what direction is the duck moving relative to the airplane.

Question

vikas askiitian expert · Answer

velocity of duck = V d = 20i + 40j velocity of aeroplane V a = -80i + 40j velocity of duck wrt plane = V ad = V d - Va = 100 i ans cos@ = a.b/(ab) (@ is angle with duck is moving wrt plane) (a.b = dot product ) = -2/root5 @ = cos -1 (-2/root5) ans approve if u like my ans
