A jet plane is speeding down the runway during takeoff. Air resistance is not negligible. Identify the forces on the jet.

Weight , Drag , Thrust , Normal force

Explanation:

It is given that a jet plane is speeding during takeoff. The air resistance is negligible.

Therefore, the forces that acts on the jet plane are :

Weight

As the plane has some mass, the weight of the plane is acted upon it. The weight is acted in the downward direction.

Normal force or the Lift

The lift force is the force that helps the plane to move up in the air and it opposes the weight of the plane. It is the normal force to the weight of the plane and this force holds the plane in the air.

Thrust

The thrust force is the force which helps to move an aircraft in the direction of the motion. This force is created by the jet engine. This force moves the plane in the forward direction through the air.

Drag

Drag force is caused due to the difference in the velocity of the solid objects and the air. The drag force opposes the forward motion of the jet plane.  

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
