please help
A uniform disk of radius 0.65 m rotates clockwise about its central axis and accelerates with constant angular acceleration. At time 1-0 it is rotating at 34 rad/s, at timeに15 s later, its angular speed is 13 rad/s. (Recall 2π rad-1 rev). a. What is the direction of the angular velocity? b. What is the direction of the angular acceleration? c. Calculate the magnitude of the angular acceleration d. Through how many radians has the disk turned in...

These questions are to be answered using MATLAB. I only
need #3 answered, but #1 provides information (like initial
velocity, etc.) required for the questions. I think I have it done,
but I'd like to see if there are other ways to use MATLAB for this
question.
