Question

What does the expression “75 meters per second southeast” best describe?

Answer 1

Velocity because it has speed, along with direction.

Velocity is also a vector because it has both direction and magnitude.

Southeast is the direction of velocity while 75 m/s or instantaneous speed (meters per second) is the magnitude of velocity.

This is also equal to 270,000 meters an hour(m/h) or around 167.81 miles an hour(mph) or 270 kilometers an hour(km/h)

To convert seconds to seconds in an hour, multiply by 3600 because there are 60 seconds in a minute, and 60 minutes in an hour.

There are 1000 kilometers in an hour.

There are 1609.34 or 1609 meters in a mile so you divide this factor to get the miles per hour.

Answer 2

Explanati D. velocity.

Velocity is equivalent to a specification of its speed and direction of motion, for example 300 km/h to the east.

Velocity is a physical vector quantity (measured in metres per second) and need magnitude and direction to define it, for example 100 metres per second east.on:
