A space explorer is moving through space far from any star or planet. He notices a large rock, taken as a specimen from an alien planet, floating around the cabin. could he push is gently or kick it toward the storage compartment? Why?Gently kick it. Consider Newton's 3rd

Law, if he kicks the rock hard the rock will push back on him by similar force and he will be sent flying backwards while the rock is sent flying forwards. Another thing to remember of is there is no friction in space so once pushed lightly, the rock will continue in a straight line at a fix velocity to the other end of the compartment.
