Question:

If you are outdoors, the wind may make it feel a lot colder than the thermometer reads. You feel the windchill temperature, which, if the air temperature is 20◦F, is given in ◦F by W (v) = 48.17 − 27.2v0.16, where v is the wind velocity in mph for 5 ≤ v ≤ 60.3
(a) If the air temperature is 20◦F, and the wind is blowing at 40 mph, what is the windchill temperature, to the nearest degree?
(b) Find W¨(40), and explain what this means in terms of windchill.
