Aircraft nose down

How long will fall airliner from a height of 10000 m at speed 1,000 km/h?

Correct result:

t =  36 s

Solution:

h=10000 m v=1000 km/h m/s=1000/3.6  m/s=277.77778 m/s  s=vt  t=h/v=10000/277.7778=36 s



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
