Question

A person having a mass of 85 kg sits on the edge of a horizontal rotating platform, 2.2 m from the center of the platform, and has a tangential speed of 6.6 m/s. calculate the angular momentum of the person

Answer 1

The angular momentum of the person is given by:

`L=mvr`
where
`m=85 Kg` is the mass of the person,
`v=6.6 m/s` is the tangential velocity, and
`r=2.2 m` is the distance of the person from the center of rotation. Using these data, we find

`L=(85 Kg)(6.6 m/s)(2.2 m)=1234.2 Kg \cdot m^2/s`
