. Nick lifts 2 buckets of water up to the roof of his school. He plans to drop the water on his physics teacher. The 2 buckets are hung one above the other and pulled up the roof by a rope. The mass of the top bucket and its water is 9.00 kg, and the bottom bucket and its water has a mass of 6.00 kg. If the action reaction force between the buckets (the tension in the rope between the buckets) is 70.0 N, calculate:
