Explanation:
Given parameter
Distance = 5000km = 5 x 10⁶m
Unknown:
time taken = ?
Solution:
We use the normal speed equation to solve this problem as we take the speed of the wave to be 3 x 10⁸m/s.
Speed = ![\frac{Distance }{Time taken}](https://tex.z-dn.net/?f=%5Cfrac%7BDistance%20%7D%7BTime%20taken%7D)
Inputting the parameters:
Time taken = ![\frac{distance }{velocity of the wave}](https://tex.z-dn.net/?f=%5Cfrac%7Bdistance%20%7D%7Bvelocity%20of%20the%20wave%7D)
Time taken =
= 0.017s

Answer:
Use a faster than normal approach and landing speed.
Explanation
For pilots, it is one of the critical moments of the flight that concentrates 12% of fatal accidents. The main difficulty lies in reaching enough speed to take flight within the space of the runway. At present, it ceased to be a challenge for the aircraft, since the engine power improved, so the takeoff ceased to be the most dangerous moment of the flight.
One of the risks that aircraft face today is that some of the engines fail while the plane accelerates. In that case, the pilot must decide in an instant whether it is better to take flight and solve the problem in the air or if it is preferable not to take off.
Although for many staying on the ground might seem the most sensible option, it is not as simple as it seems: to suddenly decelerate an aircraft, with the weight it has and the speed it reaches can cause accidents. However, today a special cement was designed that runs around the runways of the airports, which when coming into contact with the wheels of the aircraft the ground breaks and helps to slow down.
Answer:

Explanation:
We are given that
Initial circumference=C=168 cm
![\frac{dC}{dt}=-15cm/s](https://tex.z-dn.net/?f=%5Cfrac%7BdC%7D%7Bdt%7D%3D-15cm%2Fs)
