If a fighter jet touches the runway at 220km/h, then decides to brake, and finally comes to a stop at 31 seconds later.

What is the shortest runway the fighter jet can land, assuming constant deceleration starting at touchdown?

Is the answer 570 meters or am I just totally off

  • Physics - ,

    1) change speed to m/s
    61.1m/s check that.



    I get considerably more than you

    Remember, under constant deaccleration to a stop, the average speed is 1/2 the initial speed.
