Coughing forces the trachea to contract, which affects the velocity v of the air passing through the trachea. suppose the velocity of the air during coughing is v = k(r-r)r2 where k and r are constants, r is the normal radius of the trachea, and r is the radius during coughing. what radius will produce the maximum air velocity?
