Suppose you are at the center of a large freely-rotating horizontal turntable in a carnival funhouse. As you crawl toward the edge, the angular momentum of you and the turntable

decreases

remains the same, but the RPMs decreas

decreases in direct proportion to your decrease in RPMs

none of these

    Answer:

    increases

    Explanation:

    The angular momentum of an object rotating about a point is given by:

    L=mvr

    where

    m is the mass of the object

    v is the velocity

    r is the distance from the centre of the circular trajectory

    In this problem, when you move towards the edge, the value of r (distance from the centre) increases. Assuming that the other quantities are not changing, this means then that the value of L, the angular momentum, is increasing.
