A jet comes in for a landing on solid ground

Click For Summary
SUMMARY

A jet landing on solid ground at a speed of 100 m/s can come to rest with a maximum deceleration of 5.00 m/s². The minimum time required for the jet to stop is 20 seconds, calculated using the formula \( t = \frac{v}{a} \). The jet requires a stopping distance of 1 km, which exceeds the available runway length of 0.800 km at the tropical island airport, making it impossible for the jet to land safely there.

PREREQUISITES
  • Understanding of kinematic equations, specifically \( v^2 = 2as \)
  • Knowledge of basic physics concepts such as acceleration and deceleration
  • Familiarity with units of measurement in physics (meters, seconds)
  • Ability to perform calculations involving speed, time, and distance
NEXT STEPS
  • Study the kinematic equations in detail, focusing on their applications in real-world scenarios
  • Learn about the principles of aircraft landing dynamics and safety requirements
  • Research the implications of runway length on aircraft operations and safety
  • Explore advanced topics in physics related to motion and forces
USEFUL FOR

Aerospace engineers, physics students, aviation safety professionals, and anyone interested in the dynamics of aircraft landings.

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.
