A long ladder 20 feet long is leaning against a wall with one end on the floor. The bottom end of the the ladder is being pulled along the floor away from the wall at a constant rate of feet/sec. Assume that the top of the ladder is always in contact with the wall. What are the velocity and acceleration of the top of the ladder when the bottom of the ladder is 12 feet from the wall?
