An astronaut accidentally gets separated out of his small spaceship accelerating in inner-stellar space at a constant rate of 100 ms-2. What is the acceleration of the astronaut the instant after he is outside the spaceship? |
|
Answer» The moment he is out of the ship, there is no external force on the astronaut. We are assuming that, there are no nearly stars or their satellites to exert gravitational force on him, and the small spaceship exerts negligible gravitational attraction on him. By the first law of motion, the acceleration of the astronaut is zero. |
