Question

There is a hoop that is moving to the right. there is also a value for kinetic and static friction. The hoop begins sliiping but then eventually rolls. That is pretty much all the data we are given for this question besides the fact that the hoop also has a mass. We think that the hoop will never stop rolling since there is no external force acting on it are we wrong?

Answer 1

Ans: You are wrong since it is slipping but the eventually rolling so it is making a point contact with the surface so there is a friction between these two surfaces.

since it is having mass then it posseses some with which in tern will have the center of mass through which all the weight will be acting so we are having a friction beacause of weight so the friction will be there and at some point of time the energy lost completely by the body so it stops.

So it will come to rest rest at some point of time.
