Question 31

Multiple Choice

A solid sphere and a solid cylinder both have the same radius and mass. If the sphere is spun about an axis through it center with angular velocity A solid sphere and a solid cylinder both have the same radius and mass. If the sphere is spun about an axis through it center with angular velocity <sub>sphere</sub>, what angular velocity must the cylinder have to the same rotational kinetic energy as the sphere? Round your answer to 2 significant figures. A) <sub>cylinder</sub> = <sub>sphere</sub> B) <sub>cylinder</sub> = 0.80 <sub>sphere</sub> C) <sub>cylinder</sub> = 0.89 <sub>sphere</sub> D) <sub>cylinder</sub> = 0.64 <sub>sphere</sub> sphere, what angular velocity must the cylinder have to the same rotational kinetic energy as the sphere? Round your answer to 2 significant figures.
