i used work energy theorem till an arbitrary distance x, and then solved for max velocity = f(x), then differentiated it = 0 to find max velocity's x, but can't seem to solve it

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.3.33m is ans
Since frictional force is proportional to the distance covered in inclined plane the question is very much similar to a spring mass system...the only difference is friction will not pull the object backward like spring does it will just retard exactly the way spring mass system retards...after you solve it you will get sinusoidal wave consider just the half part of it...then differentiate and do the rest...
just write the acc as
$$ a=gsin\theta -ugxcos\theta$$
Real potato
Now the velocity will increase only till the acc becomes zero afterwards it will retard
So just equate it to zero
solve for x and ull get 3.33m
yes i solved it that way, i wanna know why the method i mentioned above is not working
hmm smart
can you show what hve you done:uhh:
