A) \[h(1+m/M)\]
B) \[h(2-m/M)\]
C) \[2h\]
D) a function of \[m\], \[M\], \[h\] and \[u\]
Correct Answer: A
Solution :
[a] As in gravity free space displacement of centre of mass of man and ball system should not move. If displacement of the ball be h then the displacement of man in upward direction. \[mh=Mh'\Rightarrow h'=\frac{mh}{M}\] (i) Hence the position of man from ground \[H=h+h'=h=h\left[ 1+\frac{m}{M} \right]\]You need to login to perform this action.
