The motion of a sphere moving on a rough...

The motion of a sphere moving on a rough horizontal surface changes from pure sliding (without rolling) to pure rolling (without slipping). In this process, the force of friction
(`i`) intially acts opposite to the direction of motion and late in the direction of motion
(`ii`) cause linear retardation
(`iii`) causes angular acceleration
(`iv`) stops acting when pure rolling begins

A

initially acts opposite to the direction of motion and later in the direction of motion

B

cause linear retardation

C

cause angular acceleration

D

stops acting when pure rolling begains
