Solving an ODE Related to Relativistic Mass Change

In summary, an ODE (Ordinary Differential Equation) related to relativistic mass change is an equation that describes the change in mass of a moving object as it approaches the speed of light. Solving these equations is important because it allows us to understand and make accurate predictions about the behavior of objects moving at high speeds, which is essential in fields such as astrophysics and particle physics. The key principles of special relativity that are relevant to solving these ODEs are time dilation, length contraction, and the equivalence of mass and energy. Techniques such as separation of variables, substitution, and integration can be used to solve these equations, along with more advanced methods like Laplace transforms and numerical methods.

The Attempt at a Solution


Ive tried rearranging it into either a separable ODE or into the form ay'' + by' + cy = 0 but haven't gotten anywhere.

really grateful for any help :)

(I think i posted this in the wrong board...)
