A free 238U nucleus kept in atrain emits an alpha particles.When
the train is stationary, a nucleus decays and a passenger measures that the separation between the alpha particle and the recoiling nucleus becomes at time t after the decay.If the decay takes place while the train is moving at a uniform velocity v, the distance between the alpha particle and the nucleus at a time t after the decay as measured by the passenger is:
(A) x+vt (B) x-vt (c) x (D) depends on the direction of the train......
Plese don't post the solvution, only give me some hints...

49hint: what is a non-inertial frame? what is an inertial frame? what is relative velocity?
71I think since passenger is inside the train, it does not matters to him whether the train is moving or not.
