Question

The angle of elevation of aero plane from a point on the ground is 50°, after 6seconds the angle of elevation changesrupes to 60°. If the plane is flying horizontally at a height of 3000 meters . Draw the diagram related to the information.​

Answer 1

Answer:

After a flight of 30 seconds, the angle of elevation becomes 30°. If the airplane is flying at a constant height of 3000√3 m, find the speed of the airplane.
