1) Angular expression of a disk drive is given by 0(t) = a + bt + ct³, where a, b and c are constants. t is in seconds and 0 is given in radian. At the instant t = 0, 0 = "/4 and angular velocity is 2 rad/s. At t = 1.5 s, angular acceleration is 1.25 rad "//2. According to this information, (a) find constants a, b ve c with corresponding units. (b) When angle is 0 = "/4. what is the angular angular acceleration? (c) When angular acceleration is 3.5 rad s2 %3D a/2, what are the angle 0 and angular velocity?
