Question: Suppose the initial condition is y(0) = 4. Find the solution with separation of variables and graph the result. What really happens at time t

Suppose the initial condition is y(0) = 4. Find the solution with separation of variables and graph the result. What really happens at time t = 2? And what happens after this time? How does this differ from the solution of 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.
