A dentist causes the bit of a high-speed drill to accelerate from an angular speed of 1.79 x 10^4 rad/s to an angular speed of 3.13 × 10^4 rad/s. In the process, the bit turns through 3.01 x 10^4 rad. Assuming a constant angular acceleration, how long would it take the bit to reach its maximum speed of 8.46 × 10^4 rad/s, starting from rest?
