    1) An astronaut loses contact with the hull of a space station and finds himself floating 16m from the station with zero velocity relative to it. Fortunately, he is carrying a 200W flashlight. Turning on the torch he uses it as a "light rocket? If he weighs 150kg, how long will it take to get back to the ship? Is there another way he could use the flashlight to accomplish the same job of returning to the ship?
