(adsbygoogle = window.adsbygoogle || []).push({}); A fully loaded Cessna-182 airplane of mass 1260 kg has an engine failure when flying with an airspeed of 126 km/h at an altitude of 2870 m on a calm day. It then glides at a constant glide angle (which is the direction of flight below the horizontal) towards a safe landing at this constant speed of 126 km/h experiencing a drag force of 1280 N that opposes the direction in which the plane is moving.

Please use: g = 9.81 m s-2

I would like to know what equations and values i should be using to find the glide angle of the plane.

I tried using the forces given, weight and drag, with trig but as I know that the drag force is not a component force of weight I didn't have high hopes. So of course i got the wrong answer.

Will upload the working once I draw the diagram I drew in paint.

I know the answer is 5.94 degrees.

Thanking you in advance. Been banging my head around this problem I just don't see what to use to work out the glide angle.
