Probably not. The elevator has security system just like any device. It will automatically trigger breaks in case it detects some sort of free fall.
Person inside free falling elevator could experience 0G or no gravity effect something similar to what astronauts experience in earth's orbit.
The only damage that could happen to you is when the breaks are released you won't feel 0G anymore and fall about 4ft to the floor of the elevator.
Hope this helps.

sound wave is a pressure wave that results from the vibration of the particles
o the medium from the source. The motion of the particles in the medium is
parallel to the direction of the energy transport. The type of wave formed by a
sound wave is the longitudinal wave. </span>A longitudinal wave is
characterized by rarefactions. A longitudinal wave is a wave motion wherein the
particles in the wave medium are displaced parallel to transport. When motion
is detected from the source, the particle next to it vibrates from its rest
position and a progressive change in phase vibration is observed at each
particle within that wave. The result is that the energy is transported from
one region to the other. These combined motions result in the movement of
alternating regions of rarefaction in the direction of propagation.

Answer:
Explanation:
Given that
Mass of ball=0.56kg
Initial speed=17m/s
Let g=9.81m/s²
Potential energy when the ball travel half way=?
Using equation of free fall to know the maximum height the ball will reach
v²=u²-2gH.
Upward direction i.e against gravity
The the velocity at the maximum height is zero because the body will momentary stop before coming downward , therefore v=0
Therefore,
v²=u²-2gH
0²=17²-2×9.81×H
0=289-19.62H
Then, 19.62H=289
H=289/19.62.
H=14.73m
Then,
The half way is distance is ½×H=½×14.73=7.36m
Then the potential energy at this point is given as
P.E=mgh
P.E=0.56×9.81×7.36
P.E=40.43J
The potential energy halfway is 40.43J
