(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 78 revolutions per minute in 4.0 s?
(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)
