1. The problem statement
These two equations are for two different physical phenomena. The first is for a mass moving along an x axis. The mass is affected by a springforce k, a dampener with constant c and an outer force F(t), here set to .
Explanation of the second equation follows. The gist is that they are mathematically the same (I'm translating from danish, let me know if you need the rest).
a) show that both differential equations can be brought to the form:
Where and we assume
2. What I've got
I'm not even sure where to start with this.
So I'm thinking that I somehow need to use:
and possible take the integral of the whole thing. But I am pretty lost.
