Hello students, here given a migrating whale first travels 360 km northwest.
00:06
So consider directions east, west, north, south.
00:14
It is travelling northwest, so let us take here this as a vector and then it turns due north and travels 410 so that along north direction consider this as b vector.
00:31
Now we need to calculate total net magnitude and direction of the displacement.
00:37
So displacement vector will be along this direction, c vector is the displacement vector.
00:45
Here we can observe that a vector is making an angle of 45 degree.
00:53
We need to find a vector because it is having both x and y component.
01:01
So that first let us calculate a vector but magnitude of a vector is given which is 360 km and magnitude of b vector is 410 km.
01:17
As x is having both x and y component, we consider magnitude 360 along x axis cos 45 y minus i cap because it is in opposite direction travelling negative x axis plus sin 45 positive y axis hence plus j cap...
