    A weather emergency siren is mounted on a tower, 153 meters above the ground. On one hand, you would like to make the siren very loud so that it will warn as many people as possible. On the other hand, safety regulations prohibit you from exceeding an intensity level of 111 dB for workers standing on the ground directly below the siren. Assuming that the sound is uniformly emitted, what is the maximum power that the siren can put out?...

    Consider a ball of mass 0.110 kg being spun in a horizontal circle of radius r-0.50 m, as shown to the right. When the ball reaches an angular velocity (o) of 2.00 rad/s, it is given a constant angular acceleration of a- 2.00 rads. You can assume that the radius of the circular path followed by the ball remains constant during this acceleration. After precisely 3.00 seconds of this angular acceleration, the ball breaks off the string (a) In what...
