A26 foot ladder is lowered down a vertical wall at a rate of 3 feet per minute. the base of the ladder is sliding away from the wall. a. at what rate is the ladder sliding away from the wall when the base of the ladder is 10 feet from the wall? would you expect the same rate when the ladder is any distance from the wall? would you expect your answer to be positive when the base is any distance from the wall? is there a physical reason why the rate is positive? at what rate is the ladder moving away from the wall when the ladder hits the ground?
