Textbook Question
Chapter 16, Problem 23RQ
We have made many measurements of coffee cooling in a ceramic coffee cup. We realize that as the coffee cools. It gradually reaches room temperature. Consequently, we report the value of the coffee temperature in degrees above room temperature (so after a long time, the temperature rise will be equal to 0). Also, we realize that the hotter the coffee is initially (above room temperature), the longer it will take to cool. The values presented here are in degrees Fahrenheit.
Write a MATLAB function that will perform a single interpolation given five numbers as input arguments and return the interpolated value as the only function output.
Write a MATLAB program that will calculate the following scenarios. Store each part in a different variable (e.g., part (a) should be stored in a variable named PartA, part (b) should be stored in a variable named PartB, etc.),
a. What is the temperature (rise) of the cup of coffee after 37 minutes if the initial rise of temperature is 40 degrees Fahrenheit?
b. If the coffee cools for 30 minutes and has risen 14 degrees Fahrenheit at that time, what was the initial temperature rise?
c. Find the temperature rise of the coffee at 17 minutes if the initial rise is 53 degrees Fahrenheit.

With the data below solve the problems:
As we explained in earlier chapters, the
air resistance to the motion of a vehicle
is something important that engineers
investigate. The drag force acting on a
car is determined experimentally by
placing the car in a wind tunnel. The air
speed inside the tunnel is changed, and
the drag force acting on the car is
measured. For a given car, the experimental
data generally is represented by a
single coefficient that is called drag
coefficient. It is defined by the following
relationship:
F,
where
air resistance for a car that has a listed
C, = drag coefficient (unitless)
measured drag force (N)
drag coefficient of 0.4 and width of 190 cm
and height of 145 cm. Vary the air speed
in the range of 15 m/s
