Given data:
Mass of the jet;
Initial horizontal velocity of the jet while levels off,
Final horizontal velocity of the jet while levels off,
While the levels off the horizontal velocity is constant.
Initial vertical velocity of the jet while levels off,
Final vertical velocity of the jet while levels off,
Time;
Part (1),
The horizontal acceleration of the jet while levels off is given as,
Substituting all known values,
The net horizontal force on the airplane as it levels off is given as,
Substituting all known values,
Therefore, the net horizontal force on the airplane as it levels off is 0 N.
Part (2)
The vertical acceleration of the jet while levels off is given as,
Substituting all known values,
The net vertical force on the airplane as it levels off is given as,
Substituting all known values,
Therefore, the net vertical force on the airplane as it levels off is 190800 N.
