Current Attempt in Progress A dentist causes the bit of a high-speed drill to accelerate from an angular speed of 1.43 x 10 rad/s to an angular speed of 3.09 x 104 rad/s. In the process, the bit turns through 2.18 x 10 rad. Assuming a constant angular acceleration, how long would it take the bit to reach its maximum speed of 8.19 x 104 rad/s, starting from rest?

Current Attempt in Progress
A dentist causes the bit of a high-speed drill to accelerate from an angular speed of 1.43 x 10+ rad/s to an angular speed of 3.09 x 104
rad/s. In the process, the bit turns through 2.18 x 10 rad. Assuming a constant angular acceleration, how long would it take the bit to
reach its maximum speed of 8.19 x 104 rad/s, starting from rest?
