A small hoop of mass `m` is given an initial velocity of magnitude `v_(0)` on the horizontal circular ring of radius `'r'`. If the coefficient of kinetic friction is `mu_(k)` the tangential acceleration of the hoop immediately after is release is `(` assume the horizontal ring to be fixed and not in contact with any supporting surface `)`

A small bead of mass m is given an initial velocity of magnitude v_(0) on a horizontal circular wire. If the coefficient of kinetic friction is mu_(k) , determine the distance travelled before the collar comes to rest.

Choose the correct option: A small collar of mass m is given an initial velocity of magnitude v_(0) on the horizontal circular track fabricated from a slender rod. If the coefficient of kinetic friction is mu_(K) , determine the distance traveled before the collar comes to rest. (Recognize that the friction force depends on the net normal force).
