2. A dentist causes the bit of a high-speed drill to accelerate from an angular speed of 1.35 × 104 rad/s to an angular speed of 3.65 × 10¹ rad/s. In the process, the bit turns through 1.92 × 10¹ rad. Assuming a constant angular acceleration, how long would it take the bit to reach its maximum speed of 7.70 × rad/s, starting from rest?

A dentist causes the bit of a high-speed drill to accelerate from an angular speed of 1.42 x 104 rad/s to an angular speed of 3.60 x 104 rad/s. In the process, the bit turns through 2.50 x 104 rad. Assuming a constant angular acceleration, how long would it take the bit to reach its maximum speed of 9.41 x 104 rad/s, starting from rest?
