A 20-liter leaky bucket is attached to a uniform chain that weighs 0.65 kg per meter. The liquid leaks out at a uniform rate and the liquid weighs 1.1 kg per liter. If the bucket is full of water when 25 meters of chain is out and half-full when no chain is out, calculate the work done in winding the chain. O 6033 N-m 455 N-m 7025 N-m 620 N-m
