a) What is the magnitude of the tangential acceleration of a bug on the rim of a 12.0-in.-diameter disk if the disk accelerates uniformly from rest to an angular speed of 79.0 rev/min in 3.20 s?
m/s2

(b) When the disk is at its final speed, what is the magnitude of the tangential velocity of the bug?
  m/s

(c) One second after the bug starts from rest, what is the magnitude of its tangential acceleration?
