Simon drives to a restaurant where he notices that the door to the kitchen swings both in and out to allow serving staff to rapidly get to and from the kitchen. After a member of staff passes through the door it swings back and forth three times before coming to rest. The door is released a distance of 0.70 m from the frame and swings with a frequency of 0.40 Hz. b Draw a graph to show how the displacement varies with time until the door comes to rest. Include values where possible.

The ability to hear a "pin drop" is the sign of sensitive hearing. Suppose a 0.53 g pin is dropped from a height of 31 cm, and that the pin emits sound for 1.4 s when it lands. Part A Assuming all of the mechanical energy of the pin is converted to sound energy, and that the sound radiates uniformly in all directions, find the maximum distance from which a person can hear the pin drop. (This is the ideal maximum distance, but atmospheric absorption and other factors will make the actual maximum distance considerably smaller.) Express your answer using two significant figures.

Two train whistles, A and B, each have a frequency of 386 Hz . A is stationary and B is moving toward the right (away from A) at a speed of 35.0 m/s . A listener is between the two whistles and is moving toward the right with a speed of 15.0 m/s as shown in (Figure 1). What is the frequency from B as heard by the listener? What is the beat frequency detected by the listener?

Part A The ability to hear a "pin drop" is the sign of sensitive hearing. Suppose a 0.48 g pin is dropped from a height of 29 cm, and that the pin emits sound for 1.3 s when it lands. Assuming all of the mechanical energy of the pin is converted to sound energy, and that the sound radiates uniformly in all directions, find the maximum distance from which a person can hear the pin drop. (This is the ideal maximum distance, but atmospheric absorption and other factors will make the actual maximum distance considerably smaller.) Express your answer using two significant figures. km
