Answer 1

Answer:

Let distance moved by the planck be x, then wrt ground the man will move by a distance L−x

Now the net displacement of the centre of mass will be zero in ground frame

M(L−x)=M∗x/3

x=3∗L/4

(L−x)=L/4

Yeah ur right... :-{

Thx for that..

But my heart just sinks as if I've descended over a plane.. I miss her Hii in the text.. Her stpd talks for which I used to wait for hrs..
