70km/h
Velocity is a speed with a direction (e.g. 20 miles per hour North). your example is an average velocity. velocity is displacement over elapsed time. it is speed. i know this and im only 11
The average velocity of the aircraft is 212.5 km/h in the North direction. To find the average speed you must divide 850 by 4, which is 212.5. Velocity is a vector quantity which requires both a magnitude (212.5) and a direction (North).
The average velocity during that period of time is 100 kilometers per 2 hours north. It may also be stated as 50 kilometers per hour north.
It is 20 km per hour, due North.
Average velocity is simply the difference in position, divided by the time. Since you use the word "velocity" rather than "speed", a direction must be indicated. Exapmle: If you drive 100 km. due North, during 2 hours, your average velocity is 50km. per hour due North.
The change in velocity is 20 meters per second north. ( ? ? ? )
You divide the distance traveled by the time.
With the information given, it's not possible to calculate what it is now. But during that 90 minutes, its average velocity was 50 kph north.
Average velocity is a vector quantity that represents the displacement of an object divided by the time it takes to cover that displacement. It includes both the magnitude and direction of motion. Average velocity is useful for describing how an object's position changes over time.
Their average speed is the same, 5km/hour. Velocity takes both speed and direction into account. Hence Mia's average velocity was 5km/hour North, and Luisa's was 5km/hour South. Assuming they were in the same general region on Earth, this means their average velocities wee in opposite directions, but equal in magnitude.
No. The average speed is the average of the magnitude of the velocity but not the magnitude of the average of the velocity.This is because for vectors |A + B| ≤ |A| + |B|.Suppose you travel 100 metres due East at 10 metres per second and then 100 metres due North also at 10 metres per second. Your speed, throughout, is 10 metres per second and so that is your average speed.But your average velocity is the total displacement vector divided by the total time. This is100*sqrt(2) metres due NE/20 sec = 7.07 metres per second due North East.Its magnitude is 7.07 metres/sec.
What is Jack's average speed for the entire trip?
