Adentist's drill starts from rest. after 3.50 s of constant angular acceleration, it turns at a rate of 2.49 104 rev/min. (a) find the drill's angular acceleration. incorrect: your answer is incorrect. your response differs from the correct answer by more than 10%. double check your calculations. rad/s2 (along the axis of rotation) (b) determine the angle through which the drill rotates during this period. rad
