##y## would be 0 if there were no hole, no matter the time because it would be on the surface of the water. But also ##y## varies from 0 to the height of the cylinder if there is a hole.haruspex said:Yes!
Last step is to find the time taken. You need to think a bit here about the initial and final values of y. Start by imagining what would happen if there were no hole.
Since ##\frac{dy}{dt}=\frac{va}{A}## couldn't I integrate this with ##t=\int{\frac{va}{A}dy}##?
