Explanation:
Let i, j and k represents east, north and upward direction respectively.
Velocity due north,
Velocity of the crosswind,
Velocity of downdraft, (downward direction)
(a) Let v is the position vector that represents the velocity of the plane relative to the ground. It is given by :
(b) The speed of the plane relative to the ground can be calculated as :
v = 66 m/s
Hence, this is the required solution.
