Solution
Let's solve Part C by calculating the distance the plane will be from its intended position after 10 minutes if no corrective action is taken.
Given:
- Wind velocity (from the southwest) = 110 km/h
- Airplane's speed (due south) = 700 km/h
- Time = 10 minutes = hours = hours
Approach:
-
The wind blows from the southwest, which means it has a component towards the east and a component towards the north. Since the wind is coming from 45 degrees to the south and west directions, we can resolve the wind's velocity into two perpendicular components:
-
The displacement caused by the wind in 10 minutes will be the distance the wind pushes the plane in that time:
-
Calculate the resultant displacement from the intended position:
Calculation:
Let's calculate this step-by-step.The plane will be approximately 18.3 km away from its intended position after 10 minutes if no corrective action is taken.
