1.	A helicopter of mass 2000 kg rises with a vertical acceleration of 15 m//s^2. The total mass of the crew and passengers is 500 kg. Give the magnitude and direction of the : Force on the helicopter due to the surrounding air ( =10"m/s"^2).
Answer» Solution :FORCE on the HELICOPTER due to surrounding AIR is obviously a reaction. As action and reaction are equal and OPPOSITE, therefore Force of reaction F´ =62,500 vertically upwards.
