Constant speed:

  • We refer to an object as traveling at a constant speed when its speed is constant and neither rises nor falls, at a continuous rate.

Lift:

  • A force is applied to an object by a fluid flowing around it.
  • The part of this force that is perpendicular to the direction of the incoming flow is called lift.  
  • In contrast, the drag force, or portion of the force parallel to the flow direction, is the opposite.
  • Lift typically acts upward to counteract the pull of gravity, but it can also act at an angle to the flow in any direction.
  • The force is referred to as an aerodynamic force if the fluid is air.
  • It is known as a hydrodynamic force in water or any other liquid.

Solution -

The weight of the airliner is [tex]1.20[/tex] × [tex]10^{6} N[/tex] and there is an aerodynamic lift force of [tex]1.39[/tex] × [tex]10^{6} N[/tex] acting  [tex]30^{o}[/tex] to the left of the vertical.

Therefore, the airliner follows this circular path while maintaining a steady speed.
