comment Time dependence of velocity from position dependece of velocity
it could be perhaps simlified to $v(y) = \sqrt{ {C_2}*y^{C_3} - C_1 } $ by substiturion of $y = x + some const$

comment Time dependence of velocity from position dependece of velocity
aha, OK the actual function I have is a bit more complex $v(x) = \sqrt{ {C_1}( ( (x/{C_2}+1)^{C_3} - 1 } $ which is very hard to integrate analytically Is this approch applicable for If I integrate $v(x)$ numerically

comment Time dependence of velocity from position dependece of velocity
let's say $v(x) = x^2 + x $ how to integrate $\frac{dx(t)}{dt} = v(x) = x^2 + x$ ?
