Question

1. Two astronauts of the same mass and strength are planning to play catch in free space with a third astronaut, throwing him like a ball.  How many throws does the game last?

   	a.	2
   	b.	3
   	c.	4
   	d.	5
   	e.	an infinite number of throws are possible

Answer 1

Answer: 2

<<<<<<<<<<<<< Explanation >>>>>>>>>>>>>>>

as per newton's law every action has equal and opposite reaction

when one astronaut throws towards another he will start moving with similar speed in opposite direction of other astronaut .and when other astronaut catches the third astronaut he will have movement opposite to 1st one's movement and when he throws the third he will throw it slower so after 2nd throw third one will never be able to catch 1st one so answer is 2.
