The runway on which a jet lands intersects a second runway. The width of the intersection of the two runways is 30.0 m. The jet decelerates through the intersection at 5.0 m/s2, and when it clears the runway it has a final speed of
40.0 m/s. If the jet has a length of 60.0 m, how long does the jet need to clear the intersection?

2.) A plane is sitting on a runway, awaiting takeoff. On an adjacent parallel runway, another plane lands and passes the stationary plane at a speed of 39.4 m/s. The arriving plane has a length of 43.5 m. By looking out of a window (very narrow), a passenger on the stationary plane can see the moving plane. For how long a time is the moving plane visible?
