It seems like an easy problem, but so far I have had no luck. So far I have only found acceleration as a function of distance (which is quite easy), which would be [tex] a=\frac{4G\pi \rho}{3}(r-s) [/tex] (rho: Earth's density, r: Earth's radius, s: traveled distance)

But that doesn't help me since I need acceleration (or velocity) as a function of time and I have no idea how to proceed.
