Which of the following is a measurement of velocity? A)16 m east
B) 55 m/h south
C) 25 m/s2
D) 60 km/h

B) 55 m/h south

Explanation:

Velocity is the rate of displacement per unit of time.

It is mathematically expressed as:

   Velocity  =  

Displacement is the distance covered by a body in a specific direction.

Velocity is different from speed in that it specifies the direction of a body as it travels.

Therefore, we say, velocity is a scalar quantity.

When we are giving velocity values, the unit is expressed with the direction also delineated.

From the given choices, the unit with the south direction and meter per hour is obviously correct.

probably not if net force is zero
