(a) What is the tangential acceleration of a bug on the rim of a 8.0 in. diameter disk if the disk moves from rest to an angular speed of 77 rev/min in 3.0 s? (b) When the disk is at its final speed, what is the tangential velocity of the bug? (c) One second after the bug starts from rest, what is its tangential acceleration?What is its centripetal acceleration?

2. Relevant equations

a_{c}= v_{T}^{2}/ R

3. The attempt at a solution

I got all of the answers in italics, I just can;t figure out the bold part.

answers in italics:

a. a=0.273 m/s^{2}

b. v_{T}=0.819 m/s

c. a=0.273 m/s^{2}

d. a_{c}= 0.819 m/s^{2}/ 0.1016

a_{c}= 6.60 m/s^{2}
