Question

A boy walks 8 meters East, 4 meters South, 8 meters West , and finally 4 meters North. The entire motion lasted for 24 seconds.

Answer 1

Answer:

Explanation:

GIVEN :-

⇒A physics teacher walked in four direction -

⇒ North = 2 meter

⇒ South = 2 meter

⇒ East =  4 meter

⇒ West = 4 meter

TO FIND :-

⇒ What is the total distance travelled?

⇒What is the boy’s displacement from P?

SOLUTION ;-

⇒ Let us first find the total distance travelled by the physics teacher -

⇒ Total. distance travelled = North + South + East + west

⇒ 2 + 2+ 4 + 4                        

⇒ 12 meter

⇒!2 meter is the distance travelled by the physics teacher.

--------------------------------------------------------------------------------------------

⇒ Now let us find the displacement of the teacher-

The displacement of the physics teacher is 0 because when the teacher walks towards  2 metre north which gets cancelled when she walks towards 2 metre south ,  and also when she walks 4 meter east so this gets cancelled by 4 meter west ,  so hence her dislacement is 0 .

Hope you understand .
