A disc of mass `m` and radius `R` rotating with angular speed `omega_(0)` is placed on a rough surface (co-officient of friction `=mu`). Then

A disc of radius R is rotating with an angular speed omega_0 about a horizontal axis. it is placed on a horizontal table. The coefficient of kinetic friction is mu_k . What condition should be satisfied for rolling to begin?

A disc of radius R is rotating with an angular speed omega_0 about a horizontal axis. it is placed on a horizontal table. The coefficient of kinetic friction is mu_k . Calculate the time taken for the rolling to begin.

A disc of radius R is rotating with an angular speed omega_0 about a horizontal axis. it is placed on a horizontal table. The coefficient of kinetic friction is mu_k . What was the velocity of its centre of mass before being brought in contact with the table?

A ring of mass m and radius R is placed on a rough horizontal surface (co-efficient of friction mu ) with velocity of C.M. v_(0) and angular speed (2V_(0))/(R ) as shown in figure. Initially the ring is rolling with slipping but attains pure rolling motion after some time t . Then
