When a foreign object lodged in the trachea (windpipe) forces a person to cough, the diaphragm thrusts upward causing an increase in pressure in the lungs. This is accompanied by a contraction of the trachea, making a narrower channel for the expelled air to flow through. For a given amount of air to escape in a fixed time, it must move faster through the narrower channel than the wider one. The greater the velocity of the air- stream, the greater the force on the foreign object. X rays show that the radius of the circular tracheal tube contracts to about two-thirds of its normal radius during a cough. According to a mathematical model of coughing, the velocity *v* of the air- stream is related to the radius *r* of the trachea by the equation

where *k* is a constant and r_{0} is the normal radius of the trachea. The restriction on *r* is due to the fact that the tracheal wall stiffens under pressure and a contraction greater than

(a) Determine the value of *r* in the interval
*v* has an absolute maximum. How does this compare with experimental evidence?

(b) What is the absolute maximum value of *v* on the interval?

(c) Sketch the graph of *v* on the interval
