On the Moon's surface, lunar astronauts placed a corner reflector, off which a laser beam is periodically reflected. The distanc
e to the Moon is calculated from the round-trip time. The Earth's atmosphere slows down light. Assume the distance to the Moon is precisely 3.84 × 10 8 m 3.84×108 m , and Earth's atmosphere (which varies in density with altitude) is equivalent to a layer 25.0 km 25.0 km thick with a constant index of refraction n = 1.000293 n=1.000293 . What is the difference in travel time for light that travels only through space to the moon and back and light that travels through the atmosphere and space? difference in travel time:

Answer:
Explanation:
Given that,
Initial velocity of an object, u = 22 m/s
Final velocity of an object, v = 36 m/s
Time, t = 5 s
It can be assumed to find the average acceleration of the object instead of average velocity.
The change in velocity per unit time is equal to average acceleration of an object. It can be given by :
So, the acceleration of the object is .
