An observer standing on the platform at a train station watches a train pass by. Through the windows, the observer on the platform can see a passenger moving inside the
train. Rank the following situations from fastest to slowest relative speed for the observer and passenger. The speed and direction of the passenger is given compared to the
floor of the train. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.)
%3D
A. Train moves 19.0 mph east; passenger moves 8.00 mph east.
B. Train moves 21.0 mph east; passenger moves 8.00 mph west.
C. Train moves 17.0 mph east; passenger moves 9.00 mph east.
D. Train moves 20.0 mph east; passenger is at rest (not moving).

- A man is running on a straight road perpendicular to a train track and away from the track at a speed of 12 m/s. The train is moving with a speed of 30 m/s with respect to the track. What is the speed of the man with respect to a passenger sitting at rest in the train?arrow_forwardChoose the option from each pair that makes the following statement correct. Because for an object in relative motion is always [(a) greater, (b) less] than 1, a proper time interval tp is always [(c) longer; (d) shorter] than the time interval t and a proper length Lp is always [(e) longer; (f) shorter] than the length L.arrow_forwardWhen observed from the sun at a particular instant, Earth and Mars appear to move in opposite directions with speeds 108,000 km/h and 86,871 km/h, respectively.

- You arrange to meet a friend at 5:00 p.m. on Valentine’s Day on the observation deck of the Empire State Building in New York City. You arrive right on time, but your friend is not there. She arrives 5 minutes late and says the reason is that time runs faster at the top of a tall building, so she is on time but you were early. Is your friend right? Does time run slower or faster at the top of a building, as compared with its base? Is this a reasonable excuse for your friend arriving 5 minutes late?arrow_forwardA man standing still at a train station watches two boys throwing a baseball in a moving train. Suppose the train is moving east with a constant speed of 20 m/s and one of the boys throws the ball with a speed of 5 m/s with respect to himself toward the other boy, who is 5 m west from him. What is the velocity of the ball as observed by the man on the station?arrow_forwardAn observer in a rocket moves toward a mirror at speed v relative to the reference frame labeled by S in Figure P1.30. The mirror is stationary with respect to S. A light pulse emitted by the rocket travels toward the mirror and is reflected back to the rocket. The front of the rocket is a distance d from the mirror (as measured by observers in S) at the moment the light pulse leaves the rocket. What is the total travel time of the pulse as measured by observers in (a) the S frame and (b) the front of the rocket? Figure P1.30arrow_forward
