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

Part A)

Part B)

Explanation:

Drill starts from rest so its initial angular speed will be

now after 3.50 s the final angular speed is given as

so final angular speed is given as

now we have angular acceleration given as

Part b)

The angle through which it is rotated is given by the formula

now we have

the closer the planet is to the sun, the larger the gravity

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
