matter physics, the angular acceleration in hard!?
recordingudios professionals often use toreel Tape Reel. On deck as a tape, the tape is fired after reading a constant linear velocity of 0.381 m / s. The angular velocity of the adoption of coil is 7.5 rad / S. After 2.4 x 10 ^ 3 seconds, the coil is almost complete collection, and the average acceleration is 0017 rad / s ^ 2. Does this indicate an acceleration increase or decrease the angular velocity? Why?
Either v the linear velocity constant of the band, W the angular speed of take-up spool radius r tape in the take-up spool. Then w = v / r. In the tape is being wound on the take-up spool, the radius r of the tape that contains is increasing. Since V is constant, V / R is down, and therefore w is decreasing.
