Aplayground carousel is rotating counterclockwise about its center on frictionless bearings. a person standing still on the ground grabs onto one of the bars on the carousel very close to its outer edge and climbs aboard. thus, this person begins with an angular speed of zero and ends up with a nonzero angular speed, which means that he underwent a counterclockwise angular acceleration. the carousel has a radius of 1.66 m, an initial angular speed of 3.48 rad/s, and a moment of inertia of 124 kg·m2. the mass of the person is 46.8 kg. find the final angular speed of the carousel after the person climbs aboard.

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
