- 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)r² %3D Determine the value of r for which v is a maximum.arrow_forwardusing linear DEarrow_forwardAcceleration Due to Gravity Find the acceleration a(t) of a ball tossed vertically in the air from ground level with an initial velocity of 12 mis.
