Homework Help: Physics

Posted by Sam on Tuesday, October 23, 2012 at 8:38am.

A dentist causes the bit of a high-speed drill to accelerate from an angular speed of 1.20x10^4 rad/s to an angular speed of 3.14x10^4 rad/s. In the process, the bit turns through 1.92x10^4 rad. Assuming a constant angular acceleration, how long would it take the bit to reach its maximum speed of 7.85x10^4 rad/s, starting from rest?
