Question:
Refer to https://www.physicsforums.com/threads/rolling-motion-of-plank-and-cylinders.93329/
I am able to understand all the points until the point v_roller+rω=v_plank.
I have a tough time understanding this part.
My attempt at the question:
I think that the static friction at the top and bottom of the roller will provide the external torque. This external torque will provide the rotating motion.
V_roller is the velocity due to the friction between the ground and the roller?
rω is due to the friction between the roller and the plank?
And one more question
I know what is pure rolling but i am wondering how does non pure rolling looks like, is it rolling or not ?
