Knockout BITSAT 2021
It is an exhaustive preparation module made exclusively for cracking BITSAT..
A solid homogeneous sphere is moving on a rough horizontal surface, partly rolling and partly sliding. During this kind of motion of this sphere
total kinetic energy is conserved
angular momentum of the sphere about the point of contact with the plane is conserved
only the rotational kinetic energy about the centre of mass is conserved.
angular momentum about the centre of mass is conserved.
