2. a) A ladder 10 meters long is leaning against a vertical wall with its other end on the ground. The top end of the ladder is sliding down the wall. When the top end is 6 meters from the ground it is sliding down at 2 m/ sec . How fast is the bottom moving away from the wall at this instant? b) Bismuth-210 has a half life of 5 days. Suppose a sample originally has a mass of 800 mg. When is the mass reduced to 1 mg?
