A disk at rest experiences a constant angular acceleration for t-15 s, at the end of which it is spinning with a frequency of f 75rpm. Please answer the following questions. Randomized Variables r15s f=75 rpm ? 17% Part (a) Write an expression for the magnitude of the angular velocity of the disk after the acceleration in terms of the frequenc
Part (b) Calculate the magnitude of the angular velocity of the disk in radis at time 15 s. Part (c) Wrine an expeession for the average angular acceleration of the disk ae in terms of angular velocity Cakculate the magnitude of the average angular acceleration of the disk Qae from rest to r 15 s in rads ? 17% Part (e) write an expression for the period T of do disk in terms of 17 % Part on Calculate the magnitude of the penal of the disk rat time ,-IS s in sounds. frequency 6 8 command option
