Question

(a) What is the magnitude of the tangential acceleration of a bug on the rim of an 11.5-in.-diameter disk if the disk accelerates uniformly from rest to an angular speed of 75.0 rev/min in 4.00 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?
m/s²

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

(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
