A student stands on a table rotating with an angular speed \( \omega \) while holding two equal dumbbells at arm's length. Without moving anything else, the two dumbbells are dropped. What changes will be there in motion, if any? What would be the changes if he bring the dumbbells to keep in touch with his chest by folding his arms ? Explain.
