Finally back!!


So, I'm back from a well earned break..and i really missed posting questions. Sadly, the place I went to has little internet..but it has a good Shivratri Mela..

I had always wanted to analyze this toy (available at the fair) for its Physics. Could you do it for me??

I have assumed that the two ends, one in each hand are moved as shown with some velocity V. With what velocity does the snake-head move when the situation is as shown (ie the angle is 90*)???

All segments are of equal length 'L'..

    i m also getting 9v( root2-1)

    time is L/v*root2
    horizontal distance moved by snake head is 9(L-L/root2) (all angles become 180 degree)
    divide and get the answer
