RODRIGUES, H.; PANZA, N.; PORTES, D.  and  SOARES, A.. A model of oscillator with variable mass. Rev. mex. fís. E [online]. 2014, vol.60, n.1, pp.31-38. ISSN 1870-3542.

We discuss the general form of Newton's second law for variable mass systems. We then derive the equation of motion of one-dimensional oscillator with time-varying mass. The obtained equation of motion is then analytically solved and the solutions are represented by means of Hypergeometric functions. The work is addressed to physics class at undergraduate level.

Keywords : Newton's second law; variable mass systems; oscillators; hypergeometric functions.
