An astronaut accidentally gets separated out his small spaceship accelerating in interstellar space at a constant rate of `100ms^(-2)` . What is the acceleration of the astronaut the instant after he is outside the spaceship? (Assume that there are no nearby stars to exert gravitional force on him)

Explanation

Since there are no nearby stars to exert gravitaional force on him and the small spaceship exerts negligible gravitational attraction on him, the net force acting on the astronaut , once he is out of the spaceship, is zero. By the first law of motion the acceleration of the astronaut is zero.
