(a) What is the tangential acceleration of a bug on the rim of a5.0 in. diameter

Question

(a) What is the tangential acceleration of a bug on the rim of a5.0 in. diameter disk if the disk movesfrom rest to an angular speed of 78rev/min in 3.0 s?
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)

Explanation / Answer

(a).35m/s^2 (b)1.03756m/s (c) 3) .35m/s^2     4) .94m/s^2     5) 1.002m/s^2
