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

![**Problem 2:**
A dentist causes the bit of a high-speed drill to accelerate from an angular speed of \(1.50 \times 10^4 \, \text{rad/s}\) to an angular speed of \(3.25 \times 10^4 \, \text{rad/s}\). In the process, the bit turns through \(1.88 \times 10^4 \, \text{rad}\). Assuming a constant angular acceleration, how long would it take the bit to reach its maximum speed of \(8.00 \times 10^4 \, \text{rad/s}\), starting from rest?
