You may treat his arms as uniform rods of length 0.9 m and the rest of his body as a uniform cylinder of radius 0.190 m. Neglect the effect of the ball on his rotational inertia and on his center of mass, so that it remains in his geometrical center. .900 rad/s (c) Compare the initial and final total kinetic energy.

MY NOTES ASK YOUR TEACHER Imagine two circular plates; one is solid and the other has a hole cut out of the center. Both plates have the same radius, same thickness, and same mass. The same force F is applied tangential to the edge of each plate in such a way that the plates rotate about an axis passing through the center and perpendicular to the surface of the plates. Which one of the following statements is true regarding the angular acceleration? Both plates will rotate with the same angular acceleration. The solid plate will have the greater angular acceleration. The plate with the hole will have the greater angular acceleration. 7:29 PM y cloudy 3/31/2022
