Hi everyone.
00:01
We have a question in which we have given that a motorcycle which is moving with a speed of 5 meter per second.
00:06
That means we have given in the question the initial velocity of the motorcycle.
00:13
So the initial velocity is given in the question and let's say initial velocity is you.
00:20
So we can say that it is equal to 5 meter per second.
00:25
And also we have given that this motorcycle is accelerated to 0 .2 meter per second square.
00:31
That means acceleration is also given and this acceleration which is represented by a is equals to 0 .02 meter per second square and then we have given that so we have given that the time and we need to find the speed of the motorcycle that means we have to calculate the speed of the motorcycle after 10 seconds that means time is given and we can say that time is equal to 10 seconds so after these 10 seconds the first thing that we need to find is the velocity so we can say that the final velocity and then another thing that we need to find is the distance travel after this 10 seconds so the another thing is the distance so let's see how can we do this question so first of all finding the first part that is the a which is final velocity so for finding the final velocity what we can do we can apply the first equation of motion so from from first equation of motion, as we know that, final velocity v is equal to u plus 80, that is initial velocity plus acceleration multiplied by time.
01:42
So we can say that v is equal to u is given in the equation that is 5 plus acceleration which is 0 .02 multiplied by time which is 10.
01:50
So we can say that v is equals to 5 plus 0 .2 and which is coming out to be 5 .2.
01:59
So the final velocity of the body is 5 .2 meter per second...
