avg speed=17m/s
distance the front of jet has to go to clear the intersection: 25+59.7=84.7m
timetoclear=distance/avg speed
A Boeing 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 5.0 m/s2 and clears it with a final speed of 29 m/s. How much time is needed for the plane to clear the intersection?
First I added the width of intersection to the length of m. Which was 84.7 then I found Vo to be 41.0852 I subtracted that from the rate, subtracted that from the Vo. Anyways I always end up with the answer being 1 second and it's wrong.
