how do i find the angular momentum vector of a merry-go-round that is rotating counterclockwise at 3.14rad/sK with a radius of 1.5m and a mass 250kg. the merry-go-round is a cylinder.

The magnitude of the angular momentum is the moment of inertia times the angular velocity and its direction is along the axis of rotation with the sign dictated by the right hand rule.
