Asked by George
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

1) change speed to m/s
61.1m/s check that.
avgspeed=(vf+vi)/2=30.5m/s
distance=avgspeed*time
I get considerably more than you
Remember, under constant deaccleration to a stop, the average speed is 1/2 the initial speed.
