In a gravity free space, a man of mass M standing at a height h above

1.	In a gravity free space, a man of mass M standing at a height h above the ground throws a ball of mass m straight down with speed u. When the ball reaches the ground the distance of the man from above the ground is?
Answer» Answer: the centre of mass of the system doesn't change i.e..., change in COM=0 consider the MAN M moves a distance of X in the opposite DIRECTION (gravity free space) therefore, M(X) + m (-H) = 0

Answer»

Answer:

the centre of mass of the system doesn't change

i.e...,

change in COM=0

consider the MAN M moves a distance of X in the opposite DIRECTION (gravity free space)

therefore,

M(X) + m (-H) = 0
