Question
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 20-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?
V(r) = k (201² -³), 0≤r≤ 20
An object that has a radius of
(Type an integer or a simplified fraction.)
HE
will need maximum velocity to remove it.
Transcribed Image Text: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 20-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? V(r) = k (201² -³), 0≤r≤ 20 An object that has a radius of (Type an integer or a simplified fraction.) HE will need maximum velocity to remove it.
Expert Solution
Step 1: Given,

Given that

                                                            V left parenthesis r right parenthesis equals k left parenthesis 20 r squared minus r cubed right parenthesis comma space 0 less or equal than r less or equal than 20

Where k = Some positive constant

           r = object radius

We have to find for what size object, the maximum velocity needed to remove the object.
