When an object falls subject to air resistance, its velocity V satisfies the equation of change
.
?
Here time is measured in seconds and velocity in feet per second, and the variable r is known as the drag coefficient.
?
A: Terminal velocity for an average-sized man is 179 feet per second. Use this fact to calculate the value of the drag coefficient for an average-sized man. Suggestion: When terminal velocity is reached, 
is 0. Round your answer to two decimal places.B: An ordinary coffee filter has a terminal velocity of about 6 feet per second. Find the drag coefficient for a coffee filter. Round your answer to two decimal places.C: Based on your answer to parts A and B, would you expect the drag coefficient for a rock to be larger or smaller than that for a man?
