Question

When a jet lands on an aircraft carrier, a hook on the tail of the plane grabs a wire that quickly brings the plane to a halt before it overshoots the deck. in a typical landing, a jet touching down at 240 km/h is stopped in a distance of 95 m .\?

Answer 1

The question involves the physics of a jet landing on an aircraft carrier, requiring calculations of kinematics and dynamics such as acceleration and force. Other physics concepts in the examples include the Doppler Effect and the survival of a large fall with limited deceleration.

Step-by-step explanation:

When a jet lands on an aircraft carrier, the process involves precise physics to assure a safe and successful landing within the constricted space of the flight deck. The subject of the question encompasses concepts related to mechanics, specifically kinematics and dynamics, as it involves calculating acceleration, distances, and forces required to bring the plane to a halt safely.

In the scenario provided, where a Lockheed Martin F-35 II Lightning jet is taking off or landing, the physics calculations would involve

• Motion on a straight line
• Calculating acceleration and deceleration
• Decomposition of velocities and accelerations into vector components

Other examples in the array of questions include the Doppler Effect as a jet flies towards and away from observers, and how a pilot can potentially survive a fall from a great height by decelerating over a certain distance.

Answer 2

The problem seems to be incomplete because there is no question. However, from the problem description, the logical question is to find he acceleration needed by the jet to land on the airplane carrier. The working equation would be:

2ad = v₂² - v₁²
Since the jet stops, v₂ = 0. Substituting the values:
2(a)(95 m) = 0² - [(240 km/h)(1000 m/1 km)(1h/3600 s)]²
Solving for a,
a = -23.39 m/s² (the negative sign indicates that the jet is decelerating)
