A system conists of a merry-go round traveling with a constant angular velocity and a student to the side. As the merry-go round is in motion, the student jumps on the merry-go round. How does the angular momentum of the system before the student jumps on the merry-go round compare to the angular momentum of the system after the student jumps on the merry-go round?

- A disk initially at rest is fixed to a vertical axis of rotation and a 40 kg child is standing on the disk initially at rest 0.5 meters away from the axis of rotation. The rotational inertia of the disk is 50 kgm2. The boy pushes and jumps off the disk and the disk begins to rotate at 0.5 rad/s. Calculate the linear velocity of the child as they push off the disk. (The rotational inertia of the boy is mr2)Modem wind turbines generate electricity from wind power.
