A rod of mass `m` and length `L` is pivoted at a point `O` and kept in horizontal position as shown in figure. Now it is released from this position so that it can rotates freely about the point `O` in downward direction. When it becomes vertical

A rod is released from the horizontal position as shown. It is free to rotate about hinge. Find angular velocity of rod when it become vertical?

A rod of mass m and length l is held vertically on a smooth horizontal floor. Now it is released from this position, find the speed of its centre of mass when it makes an angle theta with the vertical.

A rod of mass m and length L is pivoted at the bottommost point O and can freely rotate about the point O . The rod is disturbed from the vertical position so that it starts rotating about O . When it makes an angle theta with the vertical

A uniform rod AB of mass m and length L rotates about a fixed vertical axis making a constant angle theta with it as shown in figure. The rod is rotated about this axis, so that point B the free end of the rod moves with a uniform speed V in the horizontal plane then the angular momentum of the rod about the axis is:
