Which of the following is an example of a velocity

Answer :

Option (2)

Explanation:

The total displacement covered divided by total time taken by an object is called the velocity of the object. It is a vector quantity. Mathematically, it is given by :

d is the displacement

t is the time taken

The quantity having both direction as well as magnitude are called vector quantity.

Option 1. shows the speed of an object as it is a scalar quantity.

Option 2. shows velocity of an object. It shows that the object is moving with a speed of 45 km/hr towards south.

Option 3. shows the acceleration of the object

Option 4. again shows the speed of the object.

Hence, this is the required solution.
