(a) Find the work required to pump the water out of the spout. (Use 9.8 m/s2 for g. Use 1000 kg/m3 as the weight density of water. Assume that a = 1.)
But the answer to this is: 705600 J

I need help with:
(b) Suppose that the pump breaks down after
4.7 × 105
J of work has been done. What is the depth of the water remaining in the tank? (Round your answer to the nearest tenth.)
