Coughing When a foreign object that is lodged in the tra-
chea (windpipe) forces a person to cough, the diaphragm
thrusts upward, causing an increase in pressure in the lungs.
At the same time, the trachea contracts, causing the expelled
air to move faster and increasing the pressure on the foreign
object. According to a mathematical model of coughing, the
velocity v (in cm/s) of the airstream through an average-
sized person's trachea is related to the radius r of the trachea
(in cm) by the function
v(r) = 3.2(1 – r)r Įsrsl
Determine the value of r for which v is a maximum.
RADIOACTIVE DECAY The radioactive element polonium
decays according to the law
Q(t) = Qo· 2-140)
%3D
where Qo is the initial amount and the time t is measured in
days. If the amount of polonium left after 280 days is
20 mg, what was the initial amount present?
