document.write( "Question 932601: an airplane touches down at a speed of 55 m/s on a runway that is 600 m long. The plane can decelerate at a uniform rate of 2.50 m/s^2. Will the plane be able to stop before the end of the runway? \n" ); document.write( "

use one of the big 4 kinematic equations:
\n" ); document.write( "vf^2 = vi^2 + 2*a*d
\n" ); document.write( "---
\n" ); document.write( "vf = velocity final
\n" ); document.write( "vi = velocity initial
\n" ); document.write( "a = acceleration
\n" ); document.write( "d = distance
\n" ); document.write( "---
\n" ); document.write( "since the airplane is decelerating to zero, vf = 0
\n" ); document.write( "---
\n" ); document.write( "0 = 55*55 + 2*(-2.5)*d
\n" ); document.write( "d = (-55*55)/(2*(-2.5))
\n" ); document.write( "d = 605 meters
\n" ); document.write( "---

\n" ); document.write( "the airplane will run off the end of the runway before it stops
