The higher that an airplane flies, the smaller the speed of sound.

The average speed of sound at sea level is about 343 meters per second or 768 mph, but The sound waves move slower the higher up in altitude you go. The speed of sound is nearly independent of pressure or density but does change with temperature, so the fact that the temperature generally decreases as altitude increases is the main cause for the lower speed of sound at the altitude of an airplane. Typically, for a plane at an altitude of 5 miles (8 kilometers, 26,000 feet) the speed of will have decreased about 10%.

At higher altitudes, the air begins to warm again, so above 10 kilometers, the speed of sound again rises.

An airplane flying from Los Angeles to New York is traveling at a velocity of 1200 kmh east there is a tail wind with a velocity of 60 kmh east what is the resultant velocity of the airplane in Kph?

The resultant velocity is calculated by adding the velocity of the airplane to the velocity of the tailwind, as they are in the same direction. Therefore, the resultant velocity of the airplane is 1260 km/h east (1200 km/h + 60 km/h).


An airplane flying from New York to Los Angeles is traveling at a velocity of 1400 kph west. There is a head wind with a velocity of 20 kph east. What is the resultant velocity of the airplane in kph?

The resultant velocity is calculated by subtracting the headwind velocity from the airplane's velocity: 1400 kph (west) - 20 kph (east) = 1380 kph (west)


What causes an airplane to change their velocity and direction?

An airplane changes its velocity and direction by adjusting its engine thrust, moving control surfaces like ailerons, elevators, and rudder, and by banking or pitching the aircraft. These actions alter the lift, thrust, and drag forces acting on the airplane, causing it to accelerate, decelerate, climb, descend, turn, or level off.


How can you calculate the acceleration of a commercial airplane?

Acceleration of a commercial airplane can be calculated by dividing the change in velocity during a specific time interval by that time interval. This can be measured using instruments like accelerometers on the airplane or by analyzing data from the airplane's flight instruments.


Why knowing the velocity of an airplane is more important to a traveller than knowing its speeda?

Knowing the velocity of an airplane (which includes the direction of motion) is more important for a traveler because it provides a more accurate indication of how long the flight will take and when they will arrive at their destination. Speed alone does not account for direction, so it's less informative compared to velocity.

What does it mean if an airplane has constant velocity?

it means that the airplane is staying in motion but will soon crash;)
