2. A dentist causes the bit of a high-speed drill to accelerate from an angular speed of 1.50 × 104 rad/s to an angular speed of 3.25 × 10* rad/s. In the process, the bit turns through 1.88 x 104 rad. Assuming a constant angular acceleration, how long would it take the bit to reach its maximum speed of 8.00 x 10ª rad/s, starting from rest? sf60 60 s
