A dentist using a dental drill brings it from rest to maximumoperating speed of 367,000 rpm in 3.2 s. Assumethat the drill accelerates at a constant rate during this time.
(a) What is the angular acceleration of the drill inrev/s2? rev/s2(b) Find the number of revolutions the drill bit makes duringthe 3.2 s time interval.
