A sphere of mass `m` and radius `r` rolls without slipping on the horizontal surface with speed `v`. During its motion it encounters a fixed rectangular block of height `h=(r )/(4)` as shown. The collision is inelastic. Find the angular speed of sphere immediately after collision. The body rolls without slipping.
