The same as that of the aircraft that he /she is in. If flying level, it would be zero.

Answer:
This the power of combination is given by
Explanation:
Let 'F' be the focal length of the combination of the two lenses and the focal length's of individual lenses be 
We know that focal length is the position of image when object is placed at infinity
Let us place the the object at infinity with respect to the first lens thus the position of image formed by the first lens shall be obtained using lens formula as

Applying values we get
Now this position of image formed by the first lens act's as object for the second lens, thus we have

Since image of an object placed at infinity will be formed at
thus the focal length of the combination of the 2 thin lenses will be 
This the power of combination is given by
(For the sake of question we assume lenses to be convex although the same procedure is valid for all other lenses)

Answer:
x = 76.5 m
Explanation:
Let's use Newton's second law at the point of contact between the wheel and the floor.
fr = m a
fr = miy N
N-W = 0
N = W
μ mg = m a
a = miu g
a = 0.600 9.8
a = 5.88 m / s²
Having the acceleration we can use the kinematic relationships to find the distance
² = v₀² + 2 a x
= 0
x = -v₀² / 2 a
Acceleration opposes the movement by which negative
x = - 30²/2 (-5.88)
x = 76.5 m
