(10 points) a leaky bucket was pulled from the ground up to 8 meters above the ground at a constant rate of 0.5 meters per second. initially, the bucket contained 25 liters of water. the water was leaking out of the bucket at a constant rate of 0.3 liters per second. assume that both the bucket and the rope have neglible weight. the acceleration due to gravity is 9.8 m/s2 . the density of water is 1 kilogram per liter. find the total amount of work done (in joules) when the bucket of water was moved from the ground to 8 meters above the ground.
