Problem 3

A 14-foot ladder rests vertically against the side of a house. An absent-minded worker begins dragging the bottom of the ladder away from the house at a rate of 2.5 feet per second, not noticing that another worker is standing at the top of the ladder. After a delayed reaction of 2 seconds, the worker on the ladder yells out. How fast is he moving down the wall when he yells?
