A mass of 0.75 kg stretches a spring 0.1 m. The mass is in a medium that exerts a viscous resistance of 48 N when the mass has a velocity of 4 . The viscous resistance is proportional to the speed of the object. m S Suppose the object is displaced an additional 0.03 m and released. m Find an function to express the object's displacement from the spring's equilibrium position, in m after t seconds. Let positive displacements indicate a stretched spring, and use 9.8 as the acceleration due to 8² gravity. u(t) =

VBR = 50 m/s a) b) c) d) VAR = 30 m/s Two cars are ini- tially 960m apart and are approaching each other at speeds of 50m/s and 30m/s relative to the road. Car B honks its horn, sending a packet of sound traveling at 340m/s relative to the road towards Car A. The sound wave will bounce off either car and instantaneously keep traveling at 340m/s relative to the road forwards or backwards at all times. (Note: Many parts of this problem do not require the previous part's solution to solve it) Find AB How long after the horn is sounded until the two cars have collided? How far will the sound wave have travelled (distance) in that time? What is As Sound, the displacement of the sound during that time?

(a) What is the intensity of a laser beam used to burn away cancerous tissue that, when 90.0% absorbed, puts 500 J of energy into a circular spot 2.00 mm in diameter in 4.00 s? (b) Discuss how this intensity compares to the average intensity of sunlight (about) and the implications that would have if the laser beam entered your eye. Note how your answer depends on the time duration of the exposure.
(a) Seismographs measure the arrival times of earthquakes with a precision of 0.100 s. To get the distance to the epicenter of the quake, geologists compare the arrival times of S- and P-waves, which travel at different speeds. If S- and P-waves travel at 4.00 and 7.20 km/s, respectively, in the region considered, how precisely can the distance to the source of the earthquake be determined? (b) Seismic waves from underground detonations of nuclear bombs can be used to locate the test site and detect violations of test bans. Discuss whether your answer to (a) implies a serious limit to such detection. (Note also that the uncertainty is greater if there is an uncertainty in the propagation speeds of the S- and P-waves.)

What is Ad when the laser beam passes through 10 cm of plasma having a density of n = 102? m?? How could this be used as a density diagnostic? The wavelength of the He-Ne laser radiation is 632.8 nm
A student lab group is brainstorming the design of anexperiment in which they wish to determine how thefrequency at which you shake a Slinky would affectthe wavelength. Which of the following describes themost effective design? 1. Shake Slinky with frequency of 1.0 Hz. Measurethe wavelength and the speed. Record data innotebook. Use a different speed and shake oncemore at 1.0 Hz. Measure and record thewavelength. Continue changing the wave speedwhile keeping frequency constant. Measure andrecord the wavelength for each trial. 2. Shake Slinky with frequency of 1.0 Hz. Measureand record the wavelength. Shake Slinky at 2.0Hz. Measure the wavelength.

Problem 1: You are hiking along a trail in a wide, dry canyon where the outdoor temperature is T = 29.5° C. To determine how far you are away from the canyon wall you yell "Hello" and hear the echo t = 2.4 s later. Randomized Variables T = 29,5° C t = 2.4 s Part (a) Calculate the speed of sound in the valley in meters per second, assuming the speed at 0° C is 332 m/s. Numeric : A numeric value is expected and not an expression. V = Part (b) How far are you from the canyon wall, in meters? Numeric : A numeric value is expected and not an expression. D = Part (c) If you stood at the same point on a cold morning where the temperature was T2 = -4.5 degrees C, how long would it have taken for you to hear the echo, in seconds? Numeric : A numeric value is expected and not an expression. t2
