2. If a train is traveling east at 75 kilometers per hour, what is its velocity?
Vedmedyk [2.9K]

75km/hr due east

Explanation:

The velocity of the train will be 75km/hr due east.

  • Velocity is given as the rate of change of displacement with time.

            Velocity = \frac{displacement}{time taken}

  • Velocity is a vector quantity that has both magnitude and directions.
  • It is different from speed because it has the directional attribute.
  • From the given data, we know that the train is moving at 75km per hour. This is the speed of the train.
  • If we incorporate the direction then we have its velocity.
