MCQ
When a rolling body enters onto a smooth horizontal surface, it will ............
  • ✓
    Continue rolling
  • B
    Starts slipping
  • C
    Come to rest
  • D
    Slipping as well as rolling
✓

Answer

Correct option: A.
Continue rolling
a
(a)

Smooth surface won't be able to change $w$ or $v$ of the body. So to conserve its angular momentum it will continue to roll on the smooth surface.
