Answer:
therefore horizontal displacement changes increasing with linear velocity
Explanation:
Since the plane flies horizontally, the only speed that exists is
       v₀ₓ = 55.0 m / s
the time is the time it takes to reach the floor, which we can find because the speed on the vertical axis is zero
        y =y₀ + v₀ t - ½ g t2
        0 = I₀ + 0 - ½ g t2
        t = √ 2y₀o / g
time is that we use to calculate the x-axis displacement
 The distance it travels to reach the floor is
       x = v t
       x = 55 12
       x = 660 m
When the speed horizontally the time remains the same and 120
       x ’= v’ 12
therefore horizontal displacement changes increasing with linear velocity
