When a train stops suddenly, passengers in the running train feel an instant jerk in the forward direction because

The back of seat suddenly pushes the passengers forward

Inertia of rest stops the train and takes the body forward

Upper part of the body continues to be in the state of motion whereas the lower part of the body in contact with seat remains at rest

Nothing can be said due to insufficient data

Solution

This is due to inertia. When the speeding bus stops suddenly, lower part of the body comes to rest while the upper part of the body tends to maintain uniform motion. Hence, the passenger's are thrown forward.

An astronaut accidentally gets separated out of his small spaceship accelerating in inter stellar space at a constant rate of $100 \;m/s^2$. What is the acceleration of the astronaut the instant after he is outside the spaceship ? (Assume that there are no nearby stars to exert gravitational force on him.)
