Once it hits the runway, how long till the Jet stops?

Click For Summary
SUMMARY

A jet plane landing at a velocity of 101 meters/second can come to a complete stop in approximately 19.8 seconds, given its deceleration rate of -5.1 meters/second². The calculations utilize the equation v = v0 + at to determine the time until the jet stops. Additionally, the runway length of 0.80 x 109 μ meters (or 800,000 meters) is sufficient for the plane to land safely, as the stopping distance is calculated to be 1980.2 meters.

PREREQUISITES
  • Understanding of basic kinematics equations
  • Familiarity with concepts of velocity and acceleration
  • Knowledge of unit conversions (meters to micrometers)
  • Basic algebra skills for solving equations
NEXT STEPS
  • Study the kinematic equations in detail, focusing on their applications in real-world scenarios
  • Learn about unit conversions, specifically between meters and micrometers
  • Explore practical examples of deceleration in aviation contexts
  • Investigate the physics of landing dynamics for different types of aircraft
USEFUL FOR

Aerospace engineers, physics students, and anyone interested in the dynamics of aircraft landing procedures will benefit from this discussion.

A jet plane lands with a velocity of 101 meters/second and can accelerate at -5.1 meters/second2 when coming to a rest.

a) Once it hits the runway, how long till it stops?

b) Can this plane land on Gilligan’s Island if its runway is 0.80 x 109 μ meters long?



2. Homework Equations

v = v0 + at
x − x0 = (1/2)(v0 + v)t
x = x0 + v0t + (1/2)at^2



3. The Attempt at a Solution

I have no idea how to do this problem. I have had one physics class. Sorry guys. Your help would be great
 
Physics news on Phys.org
Sorry guys... i should of labeled the title to be something like..."distance covered with changing velocity" sorry I'm new here
