Question

A truck covers a distance of 40 km along a straight road then turn right and covers a distance 20 km,then again turns right and travel forb40 km what is the displacement of the truck​

Answer 1

GIVEN THAT :

the distance covered by the truck = 40 km,20km,40

EXPLANATION :

FIRSTIT TRAVELLED ALONG A STRAIGHT LINE

THEN IT TOOK RIGHT

THEN IT AGAIN TOOK RIGHT WHICH OS 40KM

SOLUTION:

displacement = shortest distance between initial and ending point

initial point =40

ending point =40

so initial-ending point =40-40=0 displace ment

so displacement =0

extra information

when the initial and ending point is same the displace ment will be "0"

I HOPE U UNDERSTOOD CLEARLY.

Answer 2

Answer:

the distance covered by the truck = 40 km,20km,40

FIRSTIT TRAVELLED ALONG A STRAIGHT LINE

THEN IT TOOK RIGHT

THEN IT AGAIN TOOK RIGHT WHICH OS 40KM

SOLUTION:

displacement = shortest distance between initial and ending point

initial point =40

ending point =40

so initial-ending point =40-40=0 displace ment

so displacement =0

extra information

when the initial and ending point is same the displace ment will be "o"
