Aman walked back and forth in a straight line. if he travels from point a to point b, then turns around and stops at point c, what is his total displacement after 2 minutes? a. 150 b. 350 c. 100 d.50

The answer is D.50

Hope i helped

Answer : The total displacement after 2 minutes is 50 m.

Solution :

Displacement : It is defined as the change in the position of an object. It is a vector quantity that means it has direction as well as magnitude.

In mathematical term, it is defined as,

By using this formula, we get the total displacement after 2 minutes.

Initial position, A = 0 m

Final position, C = 50 m

Now put the given values in above formula, we get

Therefore, the total displacement after 2 minutes is 50 m.
