A ball is thrown on a lawn in such a way that it initially slides with a speed $v_0$ without  rolling. It gradually picks up rotation motion. Find the speed of the ball at which there will  be rolling without slipping-

  • A

    $\frac{2}{7}\, v_0$

  • B

    $\frac{2}{5}\, v_0$

  • C

    $\frac{5}{7}\, v_0$

  • D

    $\frac{3}{5}\, v_0$

A plank is moving in a horizontal direction with a constant acceleration $\alpha \hat{ i }$. A uniform rough cubical block of side $l$ rests on the plank and is at rest relative to the plank. Let the centre of mass of the block be at $(0, l / 2)$ at a given instant. If $\alpha =g / 10$, then the normal reaction exerted by the plank on the block at that instant acts at
