When sky divers initially fall from an airplane their velocity v in miles per hour after free 60
falling d feet can be approximated by v = -Vd. (Because of air resistance, they will
11
eventually reach terminal velocity) How far do sky divers need to fall to attain a velocity of
90 miles per hour? (This value for d represents the minimum distance.)

A sky diver needs to fall about how many feet to attain a velocity of 90 mph?
