Hello students, let us have a look on this question.
00:02
So, as we can see in the diagram, we have given the force value of 50 newton, we have given the distance travelled by the block is 2 .5 meter, and finally, we will have the acceleration of 2 meter per second square, and the work done also we have given 60 joule.
00:19
First of all, we have to find the angle theta about this, where the block is moving with the force f.
00:25
So, we have to find this angle theta.
00:27
So, for that what we will do, f is equal to f dot ds, so we can write it as f d cos theta.
00:33
Moving on the value of work done is 60, force we have given 50, and the cos theta and d we have given 2 .5.
00:39
So, all this value we will get the theta is equal to 0 .99 degree.
00:43
Then we have to find second question, mass of this block...
