Homework Statement
if a disc of mas m is pure rolling , with velocity v .
the instantaneous axis of rotation would be the point of contact with the ground .
As shown in the diagram this could be considered as a disc rotating about one of the point on circumference for an instant of time .
Since this is circular motion , a centripetal force should exist .
hence
mg=mv^2/r
this gives us a limiting value of velocity .
Please correct me with this ambiguity .
Thank you
