A person coughs when a foreign object is in the windpipe. The velocity of the cough depends on the size of the object. Suppose a person has a windpipe with a 22-mm radius. If a foreign object has a radius r, in millimeters, then the velocity V, in millimeters/second, needed to remove the object by a cough is given by the following equation, where k is some positive constant. For what size object is the maximum velocity needed to remove the object? Vir)=k(22-1). Osr22 An object that has a radius of (Type an integer or a simplified fra will need maximum velocity to remove it. mm mm/second mm A person coughs when a foreign object is in the windpipe.
