**A uniform sphere of mass m and radius R is placed on a rough horizontal surface (figure) … only a translational motion, looses…**

###### Answers:

Mass of the sphere = m

Radius = R

h = height from the floor

The sphere will roll without slipping when

ω = V/R

where, v is linear velocity and to is angular velocity of the sphere.

Now, angular momentum of sphere, about centre of mass [We are applying conservation of angular momentum just before and after struck.]
