For the system I have, there are both sliding and rolling under load. Sliding and rolling directions are opposite, but the overall velocity of the system is on the sliding direction. The weal is under elasto-plastic deformation. For that system how can I accurately model friction forces? I simply use cloumb's friction but, I am confused about rolling.

Question 6.3
6.3 Consider a double mass-spring system with two masses of M and m on a frictionless surface, as shown in Figure 6.30. Mass m is connected to M by a spring of constant k and rest length lo. Mass M is connected to a fixed wall by a spring of constant k and rest length lo and a damper with constant b. Find the equations of motion of each mass. (HINT: See Tutorial 2.1.) risto M wa ww...
