Chapter 19.4, Problem 7CC
A device constructed to throw various objects can impart up to 500 joules of kinetic energy to the object being thrown. For a given mass, there is a maximum velocity that the device can throw the object. This is represented in the following diagram, and it fits a power law model. Velocities above the line cannot be achieved by the device, velocities below the line can.
Write a MATLAB program that will accept a value of mass [kg] and desired velocity [m/s] from the user and classify them as “Possible” or “Not Possible.” Three points on the line are labeled on the diagram. You must use polyfit to determine the equation of the line, and then use these values to do the classification.

This is my third time asking this question. Please DO NOT copy and paste someone else's work or some random notes. I need an answer to this question.
There is a mass attached to a spring which is fixed against a wall. The spring is compressed and then released. Friction and is neglected. The velocity and displacement of the mass need to be modeled with an equation or set of equations so that various masses and spring constants can be input into Matlab and their motion can be observed. Motion after being released is only important, the spring being compressed is not important. This could be solved with dynamics, Matlab, there are multiple approaches.
I am trying to find the gross liftoff mass of a 2 stage rocket for different values of n and plot it in MATLAB. I found the total liftoff mass for stage 1 and stage 2. Is the gross liftoff mass equal to m_i1 in the code or do you have to add m_i1 and m_i2? Also, the liftoff seems to be negative for some intial values of n? That is not feasible, right?
