2. A record has two stickers on it: one is .25m from the center, and the other is . 15m from the center. The record is initially at rest when someone turns on the record player. After 2.5s, the record is rotating at .19 clockwise revolutions per second. (Assume the angular acceleration is constant.) (a) Find the angular acceleration of the record. (b) What is the angular displacement of the record at this time? (c) How long would it take for the record to complete 4.5 clockwise revolutions? (d) Find the arc length distance, tangent velocity, tangent acceleration, centripetal accel- eration, and total acceleration (as a vector) of both stickers at 2.5s
