A uniform disc rotating at a constant speed in a vertical plane about a fixed horizontal axis, passing through the centre of the disc. A piece of disc from its rim detaches itself from the dist at the instant when it is on the same horizontal with the centre of the disc and moving upwards. Then about the fixed axis, the angular speed of the

Consider three uniform solid spheres. sphere (i ) has radius r and mass m sphere (ii) has radius r and mass 3m ,
Consider three uniform solid spheres. sphere (i ) has radius r and mass m sphere (ii) has radius r and mass 3m, sphere (iii) has radius 3r and mass ‘m’. All the spheres can be placed at the same point on the same inclined plane where they will roll without slipping to the bottom. If allowed to roll down the incline, then at the ‘bottom of the incline

A uniform rod BC with length a is attached to a light string AC. End A of the string is fixed to the ceiling and the end B of the rod is on a smooth horizontal surface. B is exactly below point A and length AB is b(a<b<2a). The system is released from rest and the rod begins to slide. Find the speed of the centre of the rod when the string becomes vertical.

A disc of radius r = 0.1 m is rolled from a point A on a track as shown in the figure. The part AB of the track is a semi-circle of radius R in a vertical plane. The disc rolls without sliding and leaves contact with the track at its highest point B. Flying through the air it strikes the ground at point C. The velocity of the center of mass of the disc makes an angle of 30∘ below the horizontal at the time of striking the ground. At the same instant, velocity of the topmost point P of the disc is found to be 6 m/s (Take g = 10 m/s^2 ).
