A small ball strikes a stationery uniform rod, which is free to rotate, in gravity-free space. The ball does not stick to the rod. The rod will rotate about

A small ball strikes at one end of a stationary uniform frictionless rod of mass m and length l which is free to rotate, in gravity-free space. The impact elastic. Instantaneous axis of rotation of the rod will pass through

An impulse J = mv at one end of a stationary uniform frictionless rod of mass m and length l which is free to rotate in a gravity-free space. The impact is elastic. Instantaneous axis of rotation of the rod will pass through

An impulse J = mv at one end of a stationary uniform frictionless rod of mass m and length l which is free to rotate in a gravity-free space. The impact is elastic. Instantaneous axis of rotation of the rod will pass through

One end of a uniform rod of mass M and length L is supproted by a frictionless hinge which can with stand a tension of 1.75 Mg . The rod is free to rotate in a vertical plane. The maximum angle should the rod be rotated from the vertical position so that when left, the hinge does not brek is (pi)/n

A uniform rod ofmass M and length L is hanging from its one end free to rotate in a veritcal plane.A small ball of equal mass is attached of the lowe end as shown. Time period of small oscillations of the rod is
