Problem 72P

A computer disk drive is turned on starting from rest and has constant angular acceleration. If it took 0.750 s for the drive to make its ?second? complete revolution, (a) how long did it take to make the first complete revolution, and (b) what is its angular acceleration, in rad/s2?

Step-by-Step Solution:

Solution 72P Step 1 of 2: In the given problem, the computer disk drive rotating with constant angular acceleration take t 20.750 s to complete second complete revolution. Here we need to calculate the time taken to complete first revolution and angular acceleration in rad per second square. Given data, Displacement , = 2 (second complete revolution) Time taken for second revolution , t =2.750 s Initial angular speed, 00 (as starts from rest) To find, Angular acceleration, = Time taken for first complete revolution, t =1

Step 2 of 2
