AN ASTRONAUT IN OPEN SPACE IS AWAY FROM HIS SPACE SHIP.HOW CAN HE RETURN ON THE ROCKET?

The astronaut will have to use a rope to get to the space ship. If he is untied then he is in big problem because in space there is nothing on which he can apply some force to push himself towards the spaceship. One way out is, he will have to throw something in the direction opposite to the spaceship to push himself towards the spaceship. This is according to the law of conservation of momentum.

He  can  apply  a  force  to  get  to  the  rocket.  He  can  move  easily,  as  there  is  no  air  in  space.
