A solid ball of mass m and radius r spinning with angular velocity ω \omega falls on a horizontal slab of mass M with rough upper surface ( coefficient of friction is u ) and smooth lower surface . Immediately after collision the normal component 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 ω \omega =5 )
