Using the expressions to the right show that L=mr x v.
You drop a mass of clay (m) onto a rotating carousel and sticks to the edge of the platform at radius (r). The carousel has a mass (M) and an angular velocity of ω0.
Find the final angular velocity (ω).
A carousel is at rest. A small child, of mass (m) runs and jumps at a velocity of (v) onto the carousel of mass (M) at the edge of radius (r).
Determine the tangential velocity of the child after jumping onto the carousel.
