Question

all the 9 speed in m/s​

Answer 1

Answer:

You can convert from m/s to km/h:

1 m/s = 3.6 km/h

1 km/h = 0.2777... m/s

Example: What is 100 km/h in m/s?

A kilometer has 1,000 meters, and an hour has 3,600 seconds, so 100 kilometers per hour is:

100 x 1,000 / 3,600 = 27.777... m/s

100 km/h = 27.78 m/s (to 2 decimal places)Velocity

Velocity is speed with a direction.

So if something is moving at 5 km/h that is a speed.

But when we say it is moving at 5 km/h westwards that is a velocity.

If something moves backwards and forwards very fast it has a high speed, but a low (or zero) velocity

Examples

100 km/h is about:

how fast we can legally go on many highways

the maximum running speed of a cheetah

half the freefall speed of a skydiver

60 km/h is about:

going very fast on a bicycle

the speed needed to go one kilometer in a minute

the speed of a racehorse on a short track

full running speed of a Bengal Tiger

1 meter per second is:

about 3.2808 feet per second

1 kilometer per hour is

about 0.9113 feet per second
