Average angular acceleration of tape deck reels
Not what you're looking for?
On a reel-to-tape deck, the tape is pulled past the playback head at a constant linear speed of 0.381 m/s.
A) Using the data in part a of the drawing, find the angular speed of the take-up reel.
B) After 2.40 x 10^3 s, the take-up reel is almost full. Find the average angular acceleration of the reel and specify whether the acceleration indicates an increasing or decreasing angular velocity?

Solution Summary
Tape moves from one diameter on a reel to a different diameter on another reel, maintaining constant surface speed but changing angular velocities and accelerations. Relation between angular velocity and linear surface velocity is explained and accelerations calculated.

No drawing accompanies this stated problem.
I have an actual reel and a reel-to-reel tape recorder and have measured the following required information:
The radius of the empty take-up reel is; r= 2.7 cm= .027 m.
The radius of the reel ...
