A light plane must reach a speed of 33m/s for takeoff.
How long a runway is needed if the (constant)acceleration is 3.0m/s^2?
:
Find the time (t) to reach 33 m/sec at 3 m/sec^2
%2833-0%29%2Ft = 3
33 = 3t
t = 11 sec to reach 33 m/sec^2
:
Find the av velocity: %2833%2B0%29%2F2 = 16.5 m/sec
:
Dist = 16.5 * 11 = 181.5 meters to reach 33 m/sec speed. runway has to be at least this long.
