A block of mass m slides down a wedge of mass M as shown . The whole system is at rest , when the height of the block is h above the ground. The wedge surface is smooth and gradually flattens. There is no friction between wedge and ground. If there would have been friction wedge and block , which of the following quantities would still remains conserved ?

A large mass M and a small mass m hang at the two ends of string passing through a smooth tube. The mass m moves around in a circular path in a horizontal plane. The length of the string from the mass m to the top of the tube of the tube is l and theta is the angle this length makes with the vertical. What should be the frequency of rotation of the mass m so that M remains stationary ?

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
