Santa’s reindeer got tired and were not able to fly to the top of the roof. So instead Santa had to climb a 40 foot ladder to get to the chimney on a 25 foot house. Unfortunately, Santa had been eating a bunch of cookies and the base of the ladder started sliding away from the house at a rate of one foot per second. He slid down until he could climb in a second floor window which was 20 feet above ground. What is the rate of change of the angle of Santa’s ladder and the ground at that instant in radians?
