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

four forces are apply thrust, normal, weight and drag

See the step by step solution

Step 1.Given information

here given that if the object is speeding down on runway during takeoff and the Air resistance is not negligible, then in this situation how many forces are present.so Identify the forces on it..

Step 2

draw the free body diagram of the jet plane

Step 3

any object who touches the surface is subject to normal force and directed to earth gravitational force.

object accelerating due the engine, so the force will be in the direction of the object which is thrust force and the drag force who oppose the movement of object in air resistance is act against direction of plane.

there are four forces are present:

normal force

gravitational force

thrust force

drag force
