Question
A cylinder rolls without slipping on a rough floor, moving with a speed v. It makes an elastic collision with smooth vertical wall. After impact
- it will move with a speed v initially
- its motion will be rolling without slipping
- its motion will be rolling with slipping initially and its rotational motion will stop momentarily at some instant
- its motion will be rolling without slipping only after some time
The correct answers are: it will move with a speed v initially, its motion will be rolling with slipping initially and its rotational motion will stop momentarily at some instant, its motion will be rolling without slipping only after some time
Let look synopsis given.

An equilateral triangle ABC formed a uniform wire has two small identical beads initially located at A. The triangle is set rotating about the vertical axis AO. Then the beads are released from rest simultaneously and allowed to slide down, one along Ab and other AC as shown. Neglecting frictional effects, the quantities that are conserved as beads slides down are:
