47618__a-joke-by-sheldon-cooper_pHere is an example of how to solve a first order ordinary differential equation using Matlab. The function in this case is that  dy/dx = – 3 y with the boundary condition that when x = 0 then y(0) = 4. This solution is applicable to solving problem 4.7 in HW8, where in this case, think of the ODE as  dZ/dt = – A V[Z(t)]  and the initial condition is that when t = 0 then Z(0) = 1.3 m. The term A is just a constant that includes all the other variables, make sure your units are all compatible. You would solve this over the time interval from 0 (tstart = 0) to say 100 minutes (tend = 100) and note when Z = 1m which means the bag is empty. Here is the program ODE

I messed up my viscosity in my calculation so the correct answer should be 2H = 0.041 microns. Several of you got this answer and if I knocked off a point let me know and I will correct your grade.
