Finding a solution for Relativistic Acceleration

[Michio Cuckoo]

I tried all my mathcad software such as Maple and I can't seem to find a solution to this time based differential equation.

Hi !

Very surprising ! They should solve this EDO without any difficulty, since it is an EDO of the "separable variables" kind. This can be handly carried out.

Whenever you have a messy-looking equation, it's sometimes helpful to at least initially, get rid of all the fluff by canonicalizing the equation. In the case above, write it simply as:

\frac{dy}{dt}=k(1-y^2/a)^{3/2}

See, just that lil' bit is good progress. Now, you can't separate variables and integrate? Telll you what, can you integrate just:

\int \frac{dy}{(1-y^2/a)^{3/2}}

I haven't tried so I don't know. You try it.

This might be a two stage process, first try a substitution of y=\sqrt{a}\sin\theta and see what you get.
