Question

(a) What is the magnitude of the tangential acceleration of a bug on the rim of a 10.5-in.-diameter disk if the disk accelerates uniformly from rest to an angular speed of 79.0 rev/min in 4.60 s?


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


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


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


(e) One second after the bug starts from rest, what is its total acceleration? (Take the positive direction to be in the direction of motion.)

magnitude	m/s2
direction	° from the radially inward direction
