Question

(a) What is the tangential acceleration of a bug on the rim of a 11.0-in.-diameter disk if the disk accelerates uniformly from rest to an angular speed of 77.0 rev/min in 3.90 s?
     m/s2

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

(c) One second after the bug starts from rest, what is its tangential acceleration?
     m/s2

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

(e) One second after the bug starts from rest, what is its total acceleration?
    

Explanation / Answer

a) 77 rev/min / 60 sec/min * 2? rad/rev / 3.90 s = 2.068 rad/s
