Homework Statement
An airplane lands and starts down the runway at a southwest velocity of 59 m/s. What is the magnitude of the constant acceleration that allows it to come to a stop in 1.2 km?
Homework Equations
Not sure
To calculate the constant acceleration of a stopping airplane, you will need to know the initial velocity (speed) of the airplane, the final velocity (zero since it has stopped), and the time it took for the airplane to come to a complete stop. You can use the formula a = (vf - vi) / t where a is the acceleration, vf is the final velocity, vi is the initial velocity, and t is the time.
The unit for acceleration in this calculation would be meters per second squared (m/s²).
No, the time is a crucial factor in calculating the acceleration of a stopping airplane. Without the time, it is not possible to determine the rate at which the airplane slowed down.
Yes, the mass of the airplane can impact its acceleration. According to Newton's Second Law of Motion, F = ma, the acceleration is directly proportional to the force applied and inversely proportional to the mass. This means that a lighter airplane would experience a greater acceleration while stopping compared to a heavier airplane.
The constant acceleration of a stopping airplane can be applied in real-life scenarios such as calculating the braking distance and time needed for an airplane to safely come to a stop on a runway. It can also be used in designing and testing braking systems for airplanes to ensure they can safely stop within a specific distance. Additionally, understanding the acceleration of a stopping airplane can aid in analyzing and improving the overall performance and safety of airplanes.
