Question

Hi please help:

Find the angular acceleration produced by the drill, assuming it to be constant

The drill used by most dentists today is powered by
a small air-turbine that can operate at angular
speeds of 350000 rpm. These drills, along with
ultrasonic dental drills, are the fastest turbines in
the world-far exceeding the angular speeds of jet
engines. Suppose a drill starts at rest and comes
up to operating speed in 2.2 s. You may want to
review (Pages 305 - 307).
