Exercise 10
Person jumping onto a rotating platform
Theory used: Conservation of angular momentumMoments of inertia of uniform bodies
A platform in the shape of a uniform disk, of mass and radius , rotates without friction about its own vertical axis at . A person of mass , with zero initial angular momentum about the axis, jumps onto the rim of the platform and stays there at rest relative to it. Treating the person as a point mass, compute the final angular velocity.
