Answer:
The answer is below
Explanation:
Because of the resistance of transmission lines, high current along the line leads to large voltage drop. This voltage drop causes low efficiency because the voltage at the receiving end is far less than that at the sending end.
Therefore there is need to transmit at a higher voltage (smaller current) than that required by distribution because of efficiency.
Hence, For safety and efficiency, the voltage must be large in the transmission lines and small in the distribution lines.
To solve this problem it is necessary to apply the concepts related to linear momentum, velocity and relative distance.
By definition we know that the relative velocity of an object with reference to the Light, is defined by

Where,
V = Speed from relative point
c = Speed of light
On the other hand we have that the linear momentum is defined as
P = mv
Replacing the relative velocity equation here we have to







Therefore the height with respect the observer is



Therefore the height which the observerd measure for her is 0.56m
