A jet travels towards a ground-based radar dish. Radar locates the jet at a distance D 16 km from the dish, at an angle e-46 above horizontal Otheexpertta. com 33% Part (a) What is the jet's horizontal distance, DH in meters, from the radar dish?
Part (b) What is the jet's vertical distance, Dv in meters, above the radar dish?
Part (c) Write an expression for the distance vector, D, in rectangular form in terms of D and θ, in a coordinate system with the dish at the origin and the unit vectors i and j in the horizontal and vertical directions.
