A solid iron sphere A rolls down an inclined plane. While an identical hollow sphere B of same mass sides down the plane in a frictionless manner. At the bottom of the inclined plane, the total kinetic energy of sphere A is. A solid iron sphere A rolls down an inclined plane.

The string is pulled vertically upwards to prevent the centre of mass from falling as the cylinder unwinds the string. The tension in the string isA uniform thin rod of length l and mass m is hinged at a distance l/4 from one of the end and released from horizontal position position as shown in figure. The angular velocity of the rod as it passes the vertical position isA smooth uniform rod of length L and mass M has two identical beads of negligible size, each of mass m, which can slide freely along the rod. Initially, the two beads are at the centre of the rod and the system is rotating with an angular velocity ω o about an axis perpendicular to the rod and passing through the midpoint of the rod (see figure). There are no external forces. When the beads reach the ends of the rod, the angular velocity of the system is
