1.	A uniform circular disc of radius r . 1placed on a rough horizontal plane has initial velocity v_(0) and an angular velocity omega_(0) as shown. The disc comes to rest after moving some distance in the direction of motion. Then
Answer» the friction force acts in the backwards direction the point of CONTACT of disc with ground has zero velocity `v_(0)` MUST be equal to `(romega_(0))/2` in magnitude `v_(0)` must be equal to `2romega_(0)` in magnitude Answer :A::C
