In this question it is given that a car is moving due west with a speed of 55 m per second and 5 second later it moves due north with a speed of 30 meter per second.
00:12
Now in the first part of the problem we have to find the magnitude and direction of the average velocity during 5 second interval.
00:20
So first of all i am showing the notation for this question.
00:29
So this is our north, this is south, this is west and this is east.
00:34
So first we have given that.
00:35
The car is moving west.
00:38
So this is the initial position of the car and it is moving in this direction.
00:47
And after that we have given that it moves due north.
00:52
So we can say that the car is moving after some time in this direction.
00:58
That is positive wide direction.
01:00
In this direction we have given the speed that is b is equal to 30 meter per second.
01:04
And in this direction we have given the speed that is u is equal to this is 55 meter per second.
01:11
And this is the resultant...
