Question

A body moves along a straight line 20m in two seconds. What is it's displacement?​

Answer 1

Answer:

speed=distance/time

in this canse

speed=displacement/time

20x2=displacement

40m=displacement

Answer 2

Answer:

20m

Step-by-step explanation:

A≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡B

consider the above diagram as a path.

A ≡≡≡≡≡≡≡≡≡↑≡≡≡≡≡≡ B

                    20m

Now I have marked the 20m (distance covered by the body)

AS WE SEE THE BODY IS MOVING IN A STRAIGHT LINE. SO THE DISPLACEMENT = DISTANCE COVERED.

∴the displacement of the body is

20m itself
