+==== Wrap-up Questions ====
+  * Did you include the hose and its water in your system? Why or why not?
+  * How long will it take for the platform to reach the required energy?
+  * Is the torque generated by the hose constant in your code? Is this realistic? Why or why not? If not, qualitatively describe what changes you could me to get a more realistic model.
+  * If there were a frictional torque present, would this potentially limit your ability to reach the required energies? Why or why not?
+  * Test your prediction by assuming a frictional torque is present using  $|\tau_{\rm fric}|=bL^{2}$ , where  $b=0.00025\,{\rm kg^{-1}m^{-2}}$
