w^2x=a .. hence w=18 and x = 2 then find the value of w^2x=a..

The actual acceleration of the bob can only be judged wrt to its position at the instant.The answer given is the maximum acceleration of the bob.

I saw this today when I saw the URL of my problem with the same name had a "-2" in it. I cut out that 2 to see who posted this problem with the same name first and found it was yours. :) Here's the link to that problem.

@Tapas Mazumdar – Hmmm i solved that problem last day only!

@Md Zuhair – My bad. I didn't see the list of solvers. Good job! If you have free time, it would be great if you post a solution to the problem too! I don't post the solution myself because I like to see the approach of somebody else to a problem. Like yesterday only, I learnt something new about limits which I had never used before. It helps to expand one's knowledge! :)

@Tapas Mazumdar – Yeah sure. Will post it today evening. My exams are over, so more or less free to post solution .
