Bubble Breaker

0 rad/s + (30.0 rad/s 2 )(2.00 s) = 84.0 rad/s; angular speed when breaker trips. (b) SET UP: Consider the motion from when the circuit breaker trips until the wheel stops. For this calculation let t = 0 when the breaker trips. t = ?; θ − θ 0 = 432 rad; ω z = 0; ω0 z = 84.0 rad/s (from part (a)) ⎛ ω0 z + ω z ⎞ ⎟t 2 ⎝ ⎠ 2(θ − θ 0 ) 2(432 rad) = = 10.3 s EXECUTE: t = ω0 z + ω z 84.0 rad/s + 0 The wheel stops 10.3 s after the breaker trips so 2.00 s + 10.3 s = 12.3 s from the beginning.…

. . . but now it was the Sharp Cereal Professor who had come back to haunt them. Played by a character actor in late middle age, the Sharp Cereal Professor was a low-key and daringly adult advertisement in a sea of animated kiddie-vid ads selling bubble gum, adventure toys, dolls, action figures . . . and rival cereals. The ad faded in on a deserted fourth- or fifth-grade classroom, a scene Saturday-morning viewers of The Bugs Bunny/Roadrunner Hour and The Drac Pack could readily…

Building and electrical contractors would want to purchase bulk quantities with price a key selection factor. Manufacturers of other forms of electrical products would want component inputs, for designing into their…

Will, after him in breathless Welsh. She had never called him “William,” only ever “Will” or his Welsh name, Gwilym. His eyes narrowed, those dark blue eyes the same color as her own. When their mother had said affectionately that Will would be a breaker of hearts when he was grown, Cecily had always looked at her dubiously.
