Hello readers. In this post I was considered the m = m_o(1 – fdect(1,1:c-1)) with m_o = 10 and fdec = 0.5. Using the equations (1.2) and (1,3) of Goldstein Book and its implementation on MATLAB Code have as result the next figures during a simulation time equal to 10. The particle of variable mass is a generalization of model, the most easy is constant mass (usual in engineering calculus)
