Question

A jetliner of mass 8.70×104 kg is in level flight when it encounters a downdraft (a downward wind) that lasts for 1.20 s . The vertical component of the jetliner's velocity is 71.5 m/s after the downdraft subsides. What is the downdraft's average force, F, on the jetliner?

Answer 1

The downdraft's average force is F= 5.18 *10⁶ N.

Step-by-step explanation:

m= 8.7 * 10⁴ kg

V= 71.5 m/s

t= 1.2 s

F*t= m*V

F= m*V/t

F= 5.18 *10⁶ N
