A pulley with two buckets are set up to pass construction waste from a building under remodeling to the ground level. At the beginning (left diagram) the left bucket has mass 16.0 kg and sits at ground level. The right bucket has mass 18.5 kg and sits at 5.0 m high. The construction worker in the building then let go of the right bucket so the buckets start to move. Ignore friction, how fast are the buckets when the right bucket is about to hit the ground (right diagram)?
