1.	a uniform circular disc of radiu8s r placed on a roughn horizontal plane has initial velocity v_(0) and an angul,ar velocity omega_(0) has shown The disc comes to rest after moving some distance in the direction of motion. Then
Answer» the friction force acting in the TOWARDS direction the POINT of CONTACT of disc with GROUND has initially zero velocity `v_(0)` must be equal to `romega_(0)//2` in magnitude `v_(0)` must be equal to `2romega_(0)` in magnitude Answer :C
