Many of the topics discussed in this chapter are useful beyond the topics of mechanical waves. It is hard to conceive of a mechanical wave with sharp corners, but you could encounter such a wave form in your digital electronics class, as shown below. This could be a signal from a device known as an analog to digital converter, in which a continuous voltage signal is converted into a discrete signal or a digital recording of sound. What is the result of the superposition of the two signals?
A pulse can be described as a single wave disturbance that moves through a medium. Consider a pulse that is defined at time t=0.00s by the equation y(s)=6.00m3x2+2.00m2 centered around x=0.00m . The pulse moves with a velocity of v=3.00m/s in the positive x-direction. (a) What is the amplitude of the pulse? (b) What is the equation of the pulse as a function of position and time? (c) Where is the pulse centered at time t=5.00s ?
Consider two wave functions y1(x,t)=Asin(kxt) and y2(x,t)=Asin(kx+t+) . The resultant wave form when you add the two functions is yR=2Asin(kx+2)cos(t+2) . Consider the case where A=0.03m1,k=1.26m1,=s1 , and =10 . (a) Where are the first three nodes of the standing wave function starting at zero and moving in the positive x direction? (b) Using a spreadsheet, plot the two wave functions and the resulting function at time t=1.00 s to verify your answer.
A narrow sound pulse (for example, a short pip by a whistle) is sent across amedium. (a) Does the pulse have a definite (i) frequency, (ii) wavelength, (iii) speed of propagation? (b) If the pulse rate is 1 after every 30 s, (that is the whistle is blown for a split of second after every 30 s), is the frequency of the note produced by the whistle equal to 1/40 or 0.05 Hz ?
Two children stretch a jump rope between them and send wave pulses back and forth on it. The rope is 3 m long, and it's mass is 0.5 kg, and the force exerted on it by the children is 40N. a) what is the linear mass density of the rope? b) what is the speed of the waves on the rope?

When a single airplane engine turns on, it rotates at 2798 rpm. Assume that the soundwave it generates matches with this rotational motion, (a) what frequency is thissound wave? (b) An airplane mechanic notices that the loudness of sound fluctuateswhen the second engine on the plane is also turns on, it vibrates two times everysecond. How fast does the second engine rotate in rpm?
Two pulses, traveling in the opposite directions, on the same string are described by the functions:Yi = (5x - 4t) + 12, and y2 = - [(5x + 4t) + 6] What is the speed of y2 wave? In which direction is y2 wave traveling? Hint: use the general definition of theWave, y = f(x-vt) At what time do the two pulses cancel out each other? i.e. the resultant y1 + Y2 = 0. I continue to get these questions wrong and I do not understand where I am messing up in the math. Please help.

You are on a 100 m long ship traveling North in the deep ocean and regular waves traveling North are passing by the ship. You observe the following : (1) when the ship bow is at a wavecrest, its stern is at a wave trough; (2) a different crest is at the bow every 20 s.a) Can the ship’s speed be determined with this information ?b) If no, what other piece(s) of information is required ?c) If yes, what is the ship speed ?
