A bug sits on the rim of a 30 cm-diameter disk. The disk accelerates uniformly from rest to an angular speed of 75.0 rev/min in 4.30 s? (10 points)
a) What is the tangential acceleration of the bug?
b) When the disk is at its final speed, what is the tangential velocity of the bug?
c) One second after the bug starts from rest, what is its centripetal acceleration?
d) One second after the bug starts from rest, what is its total acceleration (magnitude)?
e) Assume the disk is spinning counterclockwise. Sketch a diagram of the disk showing the direction of centripetal and tangential acceleration vectors of the bug.
