As you stand near a railroad track, a train passes by at a speed of 34.3 m/s while sounding its horn at a frequency of 214 Hz. What frequency fa do you hear as the train approaches you? What frequency fr do you hear while it recedes? Use 343 m/s for the speed of sound in air. fa = Hz fr = Hz

(a) In a minor rail yard accident, a runaway goods truck of mass 1.85×104 kg collides at u = 20.0 ms−1 with a stationary truck of mass 2.20×104 kg, as shown in Figure 3. The trucks lock together and travel at the same speed after the collision. Assume friction is negligible. Figure 3 Sketch of the runaway and stationary goods trucks, for use in Question 10. (i) Show that the speed of the trucks after the collision is 9.14 ms−1. (ii) One of the truck wheels can be modelled as a solid disk of radius 4.60×10−1 m and moment of inertia 36.5 kgm2. Calculate the magnitude of the wheel's angular momentum after the collision. (iii) The truck's linear velocity vector is in the positive x-direction using the Cartesian coordinate system shown in Figure 3. What is the direction of the wheel's angular momentum vector? Briefly explain your reasoning. (b) The train driver sounds the train's whistle. The whistle is a pipe that is open at one end and closed at the other, and it has a length of 0.480 m. The speed of sound in air is 343 ms−1. (i) Sketch the standing wave pattern of the air pressure in the whistle for its fundamental resonant frequency. Clearly indicate the open and closed ends of the whistle pipe. (ii) Hence calculate the frequency of the sound made by the whistle's fundamental resonance. (c) An observer standing on a bridge above the train track hears the whistle as the train approaches at a speed of 40.0 ms−1. (i) Show that the whistle frequency perceived by the observer is 13.2% greater than the frequency perceived by the driver. (ii) Describe how the sound of the whistle, as heard by the observer, will change as the train approaches and goes past the bridge.

A boy is standing at a railroad crossing for a track that runs east and west. As he faces the track, east is to his right and west is to his left. Two trains on the track some distance apart are headed west, both at speeds of 8.60 m/s, and blowing their whistles (which have the same frequency). One train is approaching him from the east and the other is traveling away from him toward the west. (Assume the speed of sound is 343 m/s.) (a) If he hears a beat frequency of 6.00 Hz, determine the frequency (in Hz) emitted by the two whistles. Hz (b) What If? What would be the frequency (in Hz ) of the beats that he hears if the lead train stops at a station (and continues to blow its whistle) while the second train continues traveling toward him? Hz

You set up two speakers 5 m apart, as shown in the figure. Both speakers emit sound at a frequency of 170 Hz. You are initially standing 1 m to the left of the leftmost speaker (see figure) at point A. At this point, what kind of interference do you experience? Take the speed of sound to be 340 m/s. constructive destructive neither constructive nor destructive QUESTION 8 If you walk 2.15 m in a direction transverse to the axis connecting the two speakers (see the figure) to point B. What type of interference do you experience at this point? constructive destructive neither constructive nor destructive
