As a NASA engineer, you are charged with the task of calculating certain performance metrics for a new rocket design. In order to do so, you will need to know the total mass ejected from the rocket’s propulsion system during a flight. The mass flow rate over the course of a test burn was recorded. From the data given in lab1_problem1.xls, plot the mass flow rate as a function of time, plot the mass ejected as a function of time, and determine the total mass ejected over the test burn. Mass ejected will be the integral of the mass flow rate with respect to time.
