Question

A man leaves his house at 7:30 a.m for a morning walk and returns back at 8:15 a.m. after covering 3km. This displacement in this time is?

Answer 1

Answer:

The displacement of the person is zero as the person returns back to his house.

Explanation:

• The displacement is termed a vector quantity.
• The shortest possible distance between the two points is called a displacement.

It is given that the person leaves his house at 7:30 a.m and returns back at 8:15 a.m. So, the initial point of the journey is the house of the person.

The final point of the journey is also the house of the person. The initial point and the final point of the journey are the same.

As the displacement is just the shortest possible distance between the endpoint and the starting point so, the displacement of the person is zero.
