You can find guidelines for posting homework on this forum here. If you have trouble with Matlab basics you may consider doing the Onramp tutorial (which is provided for free by Mathworks). If your main issue is with understanding the underlying concept, you may consider re-reading the material you teacher provided and ask them for further clarification.

I'm just waiting for an answer on what c1 and c2 are. You said you don't think they are the constants within the solution. Now - then tell us what they are.

The Mass(m)–Damper(c)–Spring(k) system 
behaves just like 
, a critically-damped system where

behaves just like , a critically-damped system where and . Therefore, the solution, or the displacement of the mass is given by
.Taking the time derivative of 
yields the velocity of the mass
yields the velocity of the mass
