(a) What is the tangential acceleration of a bug on the rim of a 13.0-in.-diameter disk if the disk accelerates uniformly from rest to an angular speed of 76.0 rev/min in 4.60 s? 0.29 m/s2
(b) When the disk is at its final speed, what is the tangential velocity of the bug? 1.3 m/s
(c) One second after the bug starts from rest, what is its tangential acceleration? 0/29 m/s2
(d) One second after the bug starts from rest, what is its centripetal acceleration? ______m/s2
(e) One second after the bug starts from rest, what is its total acceleration? ________m/s2 _______° from the radially inward direction.
