Ответ:
So distance travel by airplane before stopping is 213.637 m
Explanation:
We have given initial speed of of the airplane u = 207 km /hr
Time t = 7.43 sec
207 km/hr =
As the plane finally stops its final velocity v = 0 m/sec
According to first equation of motion v = u+at
So 0=57.5+a×7.43
a= -7.738
Now according to third equation of motion
s = 213.637 m
