If a student is spun around on a rotating chair as shown above with his arms holding barbells against his torso, what would occur if he were to suddenly spread his arms out while still spinning? Question 9 options: His spin speed would decrease because the distribution of mass on the chair would move farther from the spin axis.. His spin speed would decrease because the distribution of mass on the chair would be more equal.. His spin speed would increase because the distribution of mass on the chair would be more equal. His spin speed would stay the same due to conservation of angular momentum. His spin speed would increase because the distribution of mass on the chair would move farther from the spin axis
