Question: A Boeing 747 "Jumbo Jet" has a length of 56.1 m. The runway on which the plane lands intersects another runway. The width of the intersection is 26.3 m. The plane decelerates through the intersection at a rate of 5.52 m/s² and clears it with a final speed of 46.5 m/s.

Part A: How much time is needed for the plane to clear the intersection?

I'm looking for a brief but thorough explanation, and an example.
