Ответ:
106.1 m/s
Explanation:
The shadow of the plane is moving at the same velocity as the horizontal component of the airplane's velocity.
The horizontal component of the airplane's velocity is
where
v = 150 m/s is the velocity of the airplane
Substituting,
So, the shadow is moving at 106.1 m/s as well.
