Hi, this question says that there is a car a that travels from a to b 100 km north.
00:07
So this is point a and this is point b that is 100 km north, okay, a to b.
00:16
Then from b to c town 60 km east.
00:20
So as we know east is in positive x direction, so this is 60 kilometer east and point c.
00:26
Now from c to d, 20 kilometers south.
00:30
Suppose this is point d and it's 20 kilometer south direction.
00:37
So, this is the direction north, this is the direction south, this is east direction, this is west direction.
00:45
So north, south, east and west.
00:48
Now it is asked that what is the displacement here? so for displacement, we need to find the initial and final point.
00:56
Point.
00:57
As we know, a is the initial point and d is the final point.
01:02
So, the shortest distance between a and d will be the displacement.
01:06
So now if we join a to d and in the direction a to d, so we will get ad vector and that is the displacement vector, the shortest distance between the initial position and final position.
01:23
So now we have to find out the displacement and vector magnitude.
01:28
So now see if we extend, now see if we join these two points.
01:35
Suppose there is a point e and if we join e and d...
