Radio announcers who still play vinyl records have to be

Radio announcers who still play vinyl records have to be careful when cuing up live recordings. While studio albums have blank spaces between the songs, live albums have audiences cheering. If the volume levels are left up when the turntable is turned on, it sounds as though the audience has suddenly burst through the wall. If a turntable begins at rest and rotates through 10o in 0.5 s, how long must the announcer wait before the record reaches the required angular speed of 33.3 rev/min? Assume constant angular acceleration.
