A rod touches a disc kept on a smooth horizontal plane. If the rod moves with an acceleration `a`, the disc rolls on the rod without acceleration `a`, the disc rools on therod without slidding. Then , the acceleration of the disc w.r.t the rod is

A block slides down a plane. Inclined at 30^(@) to the horizontal, with an acceleration a. A disc rolling without slipping down the same inclined plane would have an acceleration

A force F acts tangentially at the highest point of a disc of mass m kept on a rough horizontal plane. If the disc rolls without slipping, the acceleration of centre of the disc is:

A small disc and a thin uniform rod of length l, whose mass is eta times greater than the mass of the disc, lie on a smooth horizontal plane. The disc is set in motion, in horiozontal direction and perpendicular to the rod, with velocity v, after which it elastically collides with the end of the rod. Find the velocity of the disc and the angular velocity of the rod after the collision. At what value of eta will the velocity of the disc after the collision be equal to zero? reverse its direction?

A bead of mass m moves on a rod without friction. Initially the bead is at the middle of the rod and the rod moves translationally in a vertical plane with an acceleration a_(0) in a direction forming angle theta with the horizontal as shown in the given figure. The acceleration of bead with respect to rod is

A string is wrapped over the edge a uniform disc and the free end is fixed with the ceiling. The disc moves down, unwinding the string. Find the downward acceleration of the disc.

A uniform disc of mass m is fitted (pivoted smoothly) with a rod of mass m//2 . If the bottom of the rod os pulled with a velocity v , it moves without changing its orientation and the disc rolls without sliding. The kinetic energy of the system (rod + disc) is. .
