Hi guys.. I've some discussion with my friend. We are teacher. So we must carefully to answer question for student.. there the question is
From figure below, p2 and p1 applied on plane's wings. When airplane landing/decrease altitude, which condition must occupied
A. P1=P2 and v1=v2
B. P1<P2 and v1>v2
C. P1<P2 and v1<v2
D. P1>P2 and v1>v2
E. P1>P2 and v1<v2
On my opinion, at any rate we total force by bernoully equation must upright vertical oposite weight. Because, without Force of wings plane will fall. So, when take off/increase altitude F>w .. stay at certain height F=w.. and when landing F<w.. But F must remain positive. So P1>P2 and v1<v2 (E)
At opposite, my friend though that when take off P1>P2 and when landing P1<P2.
OK guys.. may you all give us your though.. thanks.. regrads
