The angle of elevation of a jet plane from a point on the ground is 60°. After a flight of 15 seconds, the angle of elevation changes to 30°. If the jet plane is flying at a constant height of 1500√3 m, find the speed of the jet plane.
Q1. The angle of elevation of a jet plane from a point on the ground is 60°. After a flight of 15 seconds, the angle of elevation changes to 30°. If the jet plane is flying at a constant height of 1500√3 m, find the speed of the jet plane.
Answer: 200 m/s
Explanation: Using trigonometric ratios, we can find the distance traveled by the jet plane and then calculate its speed.
