Question How to model as differential equation ?

Hi guys, it's my first topic and I need to help. I have tried many many times to model this question as differential equation but I could not reach to success despite all my efforts. Can any body help me? I need to write the model of the system as differential equation but I did not understand exactly how to do. I tried many solutions but...



So we can assume:

M1 = 500KG ; M2 = 450KG
m1(t) = 150KG ; m2(t) = 120KG
k1 = 20 b1 = 10
k2 = 25 b2 = 15

Guys, please help. It is very important. I have an idea for this, while working, it came to my mind. Please think like spring, piston and mass. Like as follows :

What does "the carrier" mean?

Frankly it is not clear to me what "having parameters k and b (stopping force for position and velocity)" means. Are those parameters for friction force? That is, is the friction, or retarding force given by -(kx+ bv) where "x" is the position of the car measured from the "tip point of the carrier" and v the velocity of the car? And what is the "tip point the carrier"?
