Homework problem...?? – Vijay Murthy Apr 13 '12 at 8:52

As the FAQ says, we're not here to do your homework for you. These sorts of questions where you just post a homework problem without any attempt at solving it, much less extracting the key concept, are not allowed. – David Zaslavsky♦ Apr 13 '12 at 9:10

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, see the FAQ.

Think of the system as a double pendulum with a fixed angle between the two pendulums. You should then be able to work out the maximum kinetic energy considering that the initial energy is entirely potential.

Look at this as well.

seems so complicated, any easier method? – Mathematics Apr 13 '12 at 9:01
Think of the same situation for the simple pendulum. You pull it to one side and then let go. When is the kinetic energy maximum? And what is its value? You should be able to solve the problem now if you pay attention to energy conservation. – Vijay Murthy Apr 13 '12 at 9:06
