At a distance of 50 feet from the pad, a woman observes a helicopter taking off from a heliport. If the helicopter lifts off vertically and is rising at a speed of 44 ft/sec when it is at an altitude of 120 feet, how fast is the distance between the helicopter and the woman changing at that instant?

Make a diagram, summarize the givens. This is very similar to the problems we did in class. E-mail me your homework at jsiderer@koheletyeshiva.org
