A dentist causes the bit of a high-speed drill to accelerate from an angular speed of 1.05 × 10ʻ rad/s to an angular speed of 3.14 X 10ʻ rad/s. In the process, the bit turns through 1.88 × 10ʻ rad. Assuming a constant angular acceleration, how long would it take the bit *26. to reach its maximum speed of 7.85 × 10ʻ rad/s, starting from rest?
