Question

A body rolls without slipping on a horizontal surface, then at any moment which point has the highest velocity?

• A. A
• B. B
• C. C
• D. D

Answer 1

The correct option is A A

Lowest point C is at rest because tangential velocity and translational velocities cancel each other( $v=r\omega$) and highest point from ground A at any moment is fastest because tangential velocity and translational velocities add up being in the same direction.
