(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A particle is dropped from rest, at the surface, into a tank containing oil

The acceleration of the particle in the oil is a = g – kv

where g is the gravitational acceleration and –kv being denoted by

the resistance put on the particle by the oil.

Solve for x as a function of time!

3. The attempt at a solution

I'm attaching an image file containing my calculations.

As can be seen I get a differential equation of the second order

but as I proceed to solve this equation and try to determine the

constants the whole thing turns into ZERO?!!?! What am I doing wrong??
