A disc of radius `R` rolls without slipping at speed `v` along positive `x`-axis. Velocity of point `P` at the instant shown in Fig. is

A disc of mass m and radius R is rolling without slipping as shown in the figure. The magnitude of net velocity of the point P is (OP = R/2)

A circular disc of radius R rolls without slipping along the horizontal surface with constant velocity v_0 . We consider a point A on the surface of the disc. Then, the acceleration of point A is

A circular disc of radius R rolls without slipping along the horizontal surface with constant velocity v_0 . We consider a point A on the surface of the disc. Then, the acceleration of point A is

A disc of radius r rolls without slipping on a rough horizontal floor. If veloocity of its centre of mass is v_(0) , then velocity of point P, as shown in the figure (OP=r // 2 and angleQOP=60^(@) )is
