A dentist causes the bit of a high-speed drill to accelerate from an angular speed of 1.64 x 104 rad/s to an angular speed of 5.44 x 104 rad/s. In the process, the bit turns through 3.00 x 104 rad. Assuming a constant angular acceleration, how long would it take the bit to reach its maximum speed of 7.29 x 104 rad/s, starting from rest?
