Resultant Velocity and Wind Direction

The video tutorial explains how to calculate the resultant velocity of a plane flying north at 600 km/h when encountering wind at 100 km/h from different directions. It covers four scenarios: wind going north, wind coming from the north, wind blowing west, and wind coming from the west. The tutorial uses vector addition and Pythagorean theorem to determine the resultant speed and direction, emphasizing the importance of understanding wind direction terminology.

What is the initial speed of the plane flying north before considering any wind effects?

• 500 km/h

• 700 km/h

• 800 km/h

• 600 km/h

If the wind is blowing north at 100 km/h, what is the resultant speed of the plane?

• 800 km/h

• 500 km/h

• 600 km/h

• 700 km/h

When the wind is coming from the north, what is the resultant speed of the plane?

• 400 km/h

• 500 km/h

• 700 km/h

• 600 km/h

What is the direction of the wind when it is said to be coming from the north?

• North

• South

• East

• West

How do you calculate the resultant velocity when the wind is blowing west?

• Add the speeds directly

• Multiply the speeds

• Subtract the wind speed from the plane speed

• Use Pythagoras theorem

What is the resultant speed of the plane when the wind is blowing west?

• 600 km/h

• 700 km/h

• 608 km/h

• 500 km/h

What angle is formed between the north direction and the resultant velocity when the wind blows west?

• 5 degrees

• 9.5 degrees

• 15 degrees

• 20 degrees

When the wind is coming from the west, in which direction is it actually blowing?

• East

• West

• South

• North

What is the resultant speed of the plane when the wind is coming from the west?

• 500 km/h

• 600 km/h

• 608 km/h

• 700 km/h

What is the direction of the resultant velocity when the wind is coming from the west?

• South 9.5 degrees East

• South 9.5 degrees West

• North 9.5 degrees West

• North 9.5 degrees East
