Calculate Relative Motion of an Airplane Traveling North

What is the concept of Relative Motion?

Can you explain how Relative Motion is calculated?

Explanation of Relative Motion Calculation:

Relative motion can be defined as a change of position of an object with a point or frame of reference which may be assumed to be at rest. In the case of an airplane traveling due north with an airspeed of 190 km/h and facing a wind blowing at 86 km/h from west to east, the magnitude of degrees east of north in which the airplane will travel relative to the ground can be calculated using trigonometry.

The Y component represents the airplane's airspeed of 190 km/h heading due north, while the X component represents the wind blowing at 86 km/h from west to east. By using the tanФ = Y/X formula, we can determine the angle Ф.

Calculation:

tanФ = Y/X

Ф = tan-1(Y/X)

Ф = tan-1(190/86)

Ф = tan-1(2.209)

Ф = 65.65°

The degrees east of north = 90 - 65.65 = 24.35° (approximately 24°)

Therefore, the airplane will travel approximately 24° east of north relative to the ground.

Understanding Relative Motion:

Relative motion is a concept used to describe the change in position of an object in relation to a point or frame of reference that is assumed to be at rest. It helps us understand how an object moves in a given direction when influenced by external factors such as wind or current.

In the scenario of the airplane traveling north with a given airspeed and wind blowing from west to east, the calculation of relative motion involves breaking down the velocity components into vertical (Y) and horizontal (X) vectors. By applying trigonometric principles, we can determine the angle at which the airplane will actually travel relative to the ground.

Understanding relative motion is crucial in various fields such as physics, engineering, and navigation. It allows us to predict and analyze the movement of objects in complex situations, providing valuable insights for problem-solving and decision-making.

By mastering the concept of relative motion and its calculation methods, you can enhance your problem-solving skills and analytical abilities. Practice applying these principles to different scenarios to improve your understanding and proficiency in dealing with dynamic motion situations.
