Newton's law of inertia is a factor legs comes to halt when he jumps out of the train but opper part of the body remains in motion in the direction of motion of the train thus head will be forward when he jumpsout from a running train.

Dedicated, resourceful and goal-driven professional educator with a solid commitment.

As the man jumps out from a moving train, his feet suddenly come to rest on touching the ground while his body’s upper part continues to move forward. For this reason he falls with his head forward. So as to save himself, he should run through some distance in the forward direction.
