Consider a carousel rotating at angular velocity w6 relative to an inertial frame fixed to the ground with origin o. there is a clown on the nonrotating wall (into whose mouth you want to throw a brass ring) located at a vector position rco relative to o, the center of the carousel. you are on a horse fixed to the carousel (ignore its up-and-down motion) at position ro. what is the velocity of the clown (rate of change of rc/h) relative to you (i. e., in the body frame of the carousel) in terms of wb and rc/o? (see example 8.5.) 8.5
