We're not completely sure what you mean by "per hour per second".
Going just by what we see in the question, it's an acceleration, not a velocity.
"Six miles per hour north" would be a velocity.
20 miles per hour north is an example of
Speed = Distance divided by Time. So, speed = 75 miles divided by 2.5 hours = 75 / 2.5 = 30 miles per hour. Velocity is speed and direction, so the velocity is 30 mph Northbound.
3.00 m/s
Velocity = 790.514 m/s North (rounded)The idea is to divide the distance by the time.
Displacement: 8 m south Time: 4 seconds Therefore velocity = 2 metres per second Southwards.
30 miles per hour north
If no direction is mentioned, then you have a speed. Example: "30 miles per hour". If the direction is mentioned, then you have a velocity. Example: "30 miles per hour north".
This measure is an example of velocity, which includes both a speed and a direction.
A vector. This is because the quantity given has a magnitude (20mph) and a direction (North). It is also an example of a velocity.
-- miles per hour north -- meters per second tangential
A velocity vector includes both speed and direction.
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
Take a train going west at 100 miles per hour and another train going south at the same speed. Their velocities are different because velocity is a vector quantity that gives both speed and direction. Since they are going in different directions they have different velocities.
The change in velocity is 20 meters per second north. ( ? ? ? )
Velocity is speed and its direction. "30 miles per hour" is a speed. "30 miles per hour north" is a velocity". "30 miles per hour north" and "30 miles per hour south" are identical speeds but different velocities.
Speed is the size of velocity. But velocity also has a direction. "30 miles per hour" is speed. "30 miles per hour north" is velocity.
The quantity is (Distance/Time) with Direction Component.For example, 100 Miles per hour at 30o West of North.
