MCQ
Consider a sphere of mass $‘m’$ radius $‘R’$ doing pure rolling motion on a rough surface having velocity $\rho$ as shown in the Fig. It makes an elastic impact with the smooth wall and moves back and starts pure rolling after some time again.
  • A
    Change in angular momentum about $‘O’$ in the entire motion equals $2mv_0R$ in magnitude.
  • B
    Moment of impulse provided by the wall during impact about $O$ equals $2mv_0R$ in magnitude.
  • C
    Final velocity of ball will be $ - \frac{3}{7}{\vec v_0}$
  • All of the above
