(a) What is the tangential acceleration of a bug on the rim of a10.0 in. diameter disk if the diskmoves from rest to an angular speed of 76 rev/min in 3.0s?
1 m/s2

(b) When the disk is at its final speed, what is the tangentialvelocity of the bug?
2 m/s

(c) One second after the bug starts from rest, what is itstangential acceleration?
3 m/s2
What is its centripetal acceleration?
4 m/s2
What is its total acceleration?
5 m/s2
6°(relative to the tangentialacceleration)

How do you find θ relative to tangential acceleration? Ican't seem to get the correct answer.
