The hard disk, 3 cm in diameter, of an MP3 device starts from rest and takes 0.02 s to reach its final rotation frequency, which is 3333 rpm. Determine: (a) Angular acceleration; (b) the number of revolutions completed in 0.05 s; (c) the time required to complete the first round complete; (d) the modulus of the radial and tangential accelerations of a point in the circumference of the disk at time t = 0.01 s. (e) repeat question (d) for t = 0.03 s. reponse;1,748x10*4 2.22 trs 28ms at=4.59m/s*2 at=263m/s*2 ar=1.83 x10*3 m/s*2 at=0
