1. The problem statement, all variables and given/known data a disk rotates with constant angular accel. the initial angular speed of the disc is 2pie rad/s. After the disk rotates through 10pie rad, the ang speed is 7pie rad/s. 2. Relevant equations a. what is the mag of the angular accel? 3. The attempt at a solution alpha=delta omega/delta time omega=delta theta/delta time etiher or both?
