Hi everyone, so today i'm going to solve this question for you.
00:04
Basically in this question we have been given four options.
00:08
Let me write them for you and we have to tell which one is the correct option.
00:12
Okay.
00:12
So option a is zero second.
00:16
Option b is 2 .23 second.
00:19
Option c is 3 .47 second and option d is 4 .57 second.
00:28
Okay.
00:29
Now let let us write.
00:30
What we have been given in this question.
00:33
So in this question, the data that has been given is as follows.
00:37
So we have been given force, okay, which is equal to 7 newton.
00:43
We have also been given mass represented by m.
00:48
It is equal to 400 gram and we will have to convert it in kg because the si unit of mass is kg and we know that 1 gram is equal to 10 to the power minus 3 kg.
01:00
Okay, so mass n kg is going to be equal to 0 .4 kg.
01:06
We have also been given that acceleration has to be found because we have been given that the velocity has to be raised to 80 meter per second...
