Given acceleration and velocity; find length

Click For Summary
SUMMARY

The discussion focuses on calculating the minimum runway length required for an aircraft that accelerates from rest at 2.86 m/s² to a takeoff speed of 213 km/h. The conversion of speed from kilometers per hour to meters per second is essential, resulting in approximately 59.17 m/s. The relevant kinematic equation to determine distance without time is \(d = \frac{v^2}{2a}\), where \(d\) is distance, \(v\) is final velocity, and \(a\) is acceleration. Applying this equation yields a minimum runway length of approximately 183.5 meters.

PREREQUISITES
  • Understanding of kinematic equations
  • Ability to convert units (km/h to m/s)
  • Knowledge of basic physics concepts such as acceleration and velocity
  • Familiarity with the formula \(d = \frac{v^2}{2a}\)
NEXT STEPS
  • Study kinematic equations in detail
  • Practice unit conversion techniques, specifically speed
  • Explore real-world applications of acceleration in aviation
  • Learn about the physics of aircraft takeoff and landing
USEFUL FOR

Students studying physics, particularly those focusing on kinematics, as well as aviation enthusiasts interested in the mechanics of aircraft takeoff.

Homework Statement


An aircraft takes off at 213 km/h after accelerating from rest at 2.86 m/s2. What is the minimum runway length required?


Homework Equations





The Attempt at a Solution


I know it's super simple, but I can't figure it out. I know I have to convert 213km/hr to m/s, but then what?
