Find position of a particle at a time

- If we have a force which changes depending on the position of a particle, how can we find the position of the particle at some time $t$?
- We can find its velocity if it has travelled a given distance
~~$$ \int^{r_f}_{r_o} F(r)dr = \frac{1}{2}~~*****m_p(u_f^2 - u_o^2) $$- but this equation doesn't involve time and I don't see how we can 'generate' time from a position varying force. Any help?

Find position of a particle at a time

~~If we have a force which changes depending on the position of a particle how can we find the position of the particle at some time~~**t**?- We can find its velocity if it has travelled a given distance
