Show that the angular momentum of a particle is equal to twice the product of mass and areal velocity.

Text Solution

Verified by Experts

As the person is moving away from the edge of a circular platform towards the centre, the moment of intertia will decrease. According to law of conservation momentum. `Iomega`=constant, angular speed will increase.
