AI Thread Summary
An aircraft making an emergency landing without landing gear at a speed of 40 m/s and a friction coefficient (μ) of 0.5 will slide a significant distance before coming to rest. The equation used to calculate the stopping distance is X = 2μg/v². The initial calculation resulted in 2 meters, but a more accurate calculation suggests the distance is approximately 1600 meters. The discussion also raises a comparison to car stopping distances, questioning whether they would stop in the same distance under similar conditions. Understanding the physics behind sliding friction is crucial for accurate predictions in emergency landing scenarios.

Homework Statement


An aircraft has to make an emergancey landing on a runway
without landing gear , if the aircraft lands at 40 m\s-1
and μ is 0.5 ,
How far the aircraft slides before it comes to rest ?



Homework Equations


X=2 μ g \ v2


The Attempt at a Solution


2 x 0.5 \ 20 = 2 m ?
Using some website calculater result was : 1600 m
I'm terribly lost
 
Physics news on Phys.org
Any help please
 
Then compare with a car, do you think they equally stop at same distance.?
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
