A0.450 kg ball of play-doh hangs from the ceiling by a string. a 0.0850 kg wad of play-doh is thrown straight upward from below the ball and strikes the ball with a speed of 6.40 m/s and sticks to it. how high does the combined mass of play-doh rise above the original position of the ball of play-doh?

Awoman stands a distance d from a loud motor that emits sound uniformly in all directions. the sound intensity at her position is an uncomfortable 2.0×10-3 w/m2. at a distance 2.6 times as far from the motor, what are (a) the sound intensity and (b) the sound intensity level relative to the threshold of hearing?
