Aboeing 747 "jumbo jet" has a length of 59.7 m. the runway on which the plane lands intersects another runway. the width of the intersection is 25.0 m. the plane decelerates through the intersection at a rate of 5.4 m/s2 and clears it with a final speed of 53 m/s. how much time is needed for the plane to clear the intersection?

t = 1.48 s

Explanation:

As we know that length of the Boeing plane is

width of the intersection is given as

now we know that deceleration of the plane is given as

Also the final speed of the plane while it clears the intersection is given as

now we have

also we know that

now we have

by solving above equation we have

0.11 m/s and 0.28 m/s should be correct

if they have a finite resultant
