A pilot lands a fighter aircraft on an aircraft carrier. At the moment of touchdown, the speed of the aircraft is $160 \mathrm{mph}$. If the aircraft is brought to a complete stop in 1 sec and the deceleration is assumed to be constant, find the number of $g$ 's the pilot is subjected to during landing $\left(1 \mathrm{~g}=32 \mathrm{ft} / \mathrm{sec}^{2}\right) .$

Key Concepts

Kinematics of Constant Acceleration

This concept involves using the equations of motion to relate variables such as velocity, time, and acceleration when an object is undergoing acceleration (or deceleration) at a constant rate. It is crucial for calculating acceleration from known change in velocity over a specific time interval.

Unit Conversion

Unit conversion is essential in physics to ensure consistency across measurements, especially when converting units like miles per hour to feet per second. This allows for accurate application of formulas and comparisons, such as relating the calculated acceleration to standards like gravitational acceleration.

Gravitational Acceleration and g-Forces

Gravitational acceleration, typically defined as 32 feet per second squared (ft/s²) near the Earth's surface, serves as a reference for measuring acceleration in terms of g's. g-Forces quantify the acceleration experienced by objects relative to this gravitational acceleration, allowing one to assess the physical stresses involved in rapid deceleration.
