A solid ball of mass \( m \) and radius \( r \) spinning with angular velocity \( \omega \) falls on a horizontal slab of mass \( M \) with rough upper surface (coefficient of friction \( \mu \) ) and smooth lower
\( \mathrm{P} \) surface. Immediately after collision the normal component

W of velocity of the ball remains half of its value just before collision and it stops spinning. Find the velocity of the sphere in horizontal direction immediately after the impact (given: \( R \omega=5 \) ).
