(a) What is the magnitude of the tangential acceleration of abug on the rim of a 12.0-in.-diameter disk if the disk acceleratesuniformly from rest to an angular speed of 80.0 rev/min in 3.60s?
------m/s²

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

(c) One second after the bug starts from rest, what is themagnitude of its tangential acceleration?
----------m/s²

(d) One second after the bug starts from rest, what is themagnitude of its centripetal acceleration?
--------- m/s²

(e) One second after the bug starts from rest, what is its totalacceleration? (Take the positive direction to be in the directionof motion.)
magnitude Â Â Â Â ----------m/s²
directionÂ Â Â Â -----------Â° from the radially inward direction
