```								Suppose we have just to maintain the halicopter-car system in air 	then the wings had to apply the equal force as the gravity is applying 	but we have to go up by an acceleration of 1.4m/s2  so the effective gravity wil be (9.8+1.4)	Fnet=(15000+4500)(9.8+1.4)=you may solve	 samewise the tension in the wire(pulling the car up)	tnet=mass of the car*geff=4500*10.2=
