A 3.2 km train is moving at 87% the speed of light on a new train track. It is approaching a tunnel that is 1 km long. From the perspective of a stationary observer, can the train just fit inside the tunnel completely the moment the nose is about to come out the other side? If not, what fraction of the speed of light would it need to be moving in order to accomplish this? (use 3 sig figs for...

Doppler Effect You are waiting at a train station when an approaching express train sounds its 400 Hz horn, warning everyone to stand back from the platform as it passes. If you perceive the frequency of the horn to be 425 Hz as the train approaches, how fast must the train be moving towards you? You may assume the speed of sound is 343 m/s.
