Integrating the velocity with respect
to time t gives the distance function.
Therefore, the function of the distance is
The droplet is dropped from 800 m, so s_{0} is 800. Substituting t = 10 and s_{0} = 800 into the distance function gives the value of s_{10}.
Rearranging this equation gives
s_{10} = 900
Substituting s_{0} = 800 and s_{10} = 900 into the
distance function gives
