A collar having a mass M and negligible ...

A collar having a mass M and negligible size slides over the surface of a horizontal circular rod for which the coefficient of kinetic friction is `mu_(k)` If the colar is given a speed `v_(1)` and then released at `theta=0^(@)`, determine how far d it slides on the rod before coming to rest. Given, `M=0.75kg, r=100mm, mu_(k)=0.3,g=9.81m//s^(2),v_(1)=4m//s`.
