A jet comes in for a landing on solid ground

In summary, a jet with a speed of 100m/s and a maximum acceleration of 5.00m/s^2 needs a minimum time interval, represented by 1km, to come to rest when landing on solid ground. It is not possible for this jet to land on a small tropical island airport with a runway length of 0.800Km. This is because the minimum distance needed for the jet to come to rest is greater than the length of the runway.

Homework Statement


A jet comes in for a landing on solid ground with a speed of 100m/s, and its
acceleration can have a maximum magnitude of ##5.00m/s^2 ## as it comes to rest.

(a) From the instant the jet touches the runway, what is the minimum time
interval needed before it can come to rest?
(b) Can this jet land at a small tropical island airport where the runway is 0.800Km long?
(c) Explain your answer.

Yes. You could also use ##v^2 = 2as##.

Although, I guess you still have to explain what the ##1km## you got represents.

What is the process of a jet landing on solid ground?

The process of a jet landing on solid ground involves several steps. First, the pilot must align the jet with the runway and decrease the speed by reducing engine power. As the jet gets closer to the ground, the pilot will use the control surfaces to adjust the angle of the jet's descent. The landing gear will then be deployed, and the jet will touch down on the runway. Finally, the pilot will engage the brakes to slow down the jet and bring it to a stop.

What happens if a jet misses the runway during landing?

If a jet misses the runway during landing, it will go through a missed approach procedure. This involves climbing back into the air and circling around to make another attempt at landing. The pilot may also choose to divert to another nearby airport if necessary.

How do pilots know when to start the landing process?

Pilots use a variety of instruments and visual cues to determine when to start the landing process. These include the altimeter, which measures the altitude of the jet, and the glide slope indicator, which helps the pilot maintain the proper angle of descent. Additionally, pilots rely on visual cues such as the runway lights and the distance remaining markers on the runway.

What factors can affect the smoothness of a jet landing?

The smoothness of a jet landing can be affected by several factors. These include the wind speed and direction, the weight and balance of the jet, and the condition of the runway surface. Turbulence, weather conditions, and the pilot's skill and experience can also play a role in the smoothness of a landing.

What safety precautions are taken during a jet landing?

Several safety precautions are taken during a jet landing. The pilot will conduct a pre-landing checklist to ensure all systems are functioning properly. Air traffic control will also monitor the landing and provide guidance if necessary. The runway will be cleared of any hazards, and the landing gear and brakes will be inspected before and after the landing. Additionally, pilots undergo extensive training and follow strict procedures to ensure a safe and successful landing.
