+A sound wave that enters the human ear sets the eardrum into oscillation.

+A common device for entertaining a toddler is a jump seat that hangs from the horizontal portion of a doorframe via elastic cords. Assume that only one cord is on each side in spite of the more realistic arrangement shown. When a child is placed in the seat, they both descend by a distance $d_s$ as the cords stretch (treat them as springs). Then the seat is pulled down an extra distance $d_m$ and released, so that the child oscillates vertically, like a block on the end of a spring. Suppose you are the safety engineer for the manufacturer of the seat. You do not want the magnitude of the child's acceleration to exceed $0.20g$ for fear of hurting the child's neck. If $d_m = 10$ cm, what value of $d_s$ corresponds to that acceleration magnitude?

+Ultrasound, which consists of sound waves with frequencies above the human audible range, can be used to produce an image of the interior of a human body. Moreover, ultrasound can be used to measure the speed of the blood in the body; it does so by comparing the frequency of the ultrasound sent into the body with the frequency of the ultrasound reflected back to the body's surface by the blood. As the blood pulses, this detected frequency varies.
+
+Suppose that an ultrasound image of the arm of a patient shows an artery that is angled at \(\theta = 20^\circ\) to the ultrasound's line of travel. Suppose also that the frequency of the ultrasound reflected by the blood in the artery is increased by a maximum of \(5495\,\mathrm{Hz}\) from the original ultrasound frequency of \(5.000\,000\,\mathrm{MHz}\). The speed of sound in the human arm is \(1540\,\mathrm{m/s}\). What is the maximum speed of the blood?

+Your firm needs to haul granite blocks up a slope out of a quarry and to lower dirt into the quarry to fill the holes. You design a system in which a granite block on a cart with steel wheels (weight \( w_1 \), including both block and cart) is pulled uphill on steel rails by a dirt-filled bucket (weight \( w_2 \), including both dirt and bucket) as shown in figure. How must the weights \( w_1 \) and \( w_2 \) be related in order for the system to move with constant speed? Ignore friction in the pulley and wheels, and ignore the weight of the cable.
