Question: Suppose the initial condition is y(0) = 16. Find the solution with separation of variables and graph the result. When does the solution reach 0?

Suppose the initial condition is y(0) = 16. Find the solution with separation of variables and graph the result. When does the solution reach 0? What would the depth be at this time if draining followed the equation dy/dt = -2y?
Consider Torricelli's law of draining dy/dt = -2√y (Section 5.2, Exercise 33) with the constant set to 2.
