The time reuired kor one car to paSs is the period T elocity -wavelength:) Figure 16.7 (a) What is the frequency at which each boxcar passes? Hz (b) What is the speed of the train?
A boxcar traveling at 10 m/s approaches a string of 2 identical boxcars sitting stationary on the track. The moving boxcar collides and links with the stationary cars and they all move off together along the track. What is the final speed of the cars immediately after the collision? (You may take the mass of each boxcar to be 18,537 kg.) m/s
A train is moving pass a crossing where cars are waiting for it to pass. While waiting, the driver of the lead car becomes sleepy and rests his head on the steering wheel, unintentionally activating the car's horn. A passenger in the back of the train hears the horn's sound at a frequency of 444 Hz and a passenger in the front hears it at 415 Hz. Find the train's speed and the horn's frequency, assuming the sound travels along...
As you stand near a railroad track, a train passes by at a speed of 34.1 m/s while sounding its horn at a frequency of 216 Hz. What frequency do you hear as the train approaches you and what frequency while it recedes? Take the speed of sound in air to be 344 m/s. approaching_____Hz receding______Hz
As you stand near a railroad track, a train passes by at a speed of 30.1 m/s while sounding its horn at a frequency of 218 Hz. What frequency do you hear as the train approaches you and what frequency while it recedes? Take the speed of sound in air to be 343 m/s. approaching: Hz receding:
A car moving at 90 km/h passes a 1.21 km -long train traveling in the same direction on a track that is parallel to the road. Part A If the speed of the train is 71 km/h , how long does it take the car to pass the train? Express your answer using two significant figures. Part B How far will the car have traveled in this time? Express your answer using two significant figures. Part C If the car...
Two trains of pass through the same intersection at different times. Knowing that Train B accelerates from rest at 100 m/min2 and reaches the crossing 10 min after Train A passed through. Determine the relative velocity of Train B with respect to Train A and the distance between the fronts of each train 2 min after Train B passes through the intersection. Express your answer in vector notation. 72 km/h 30° B
