Here is what I did:

distance traveled in radians = (2pi * r)(.507 revolution) = .8728 radians = θ

ω initial = v0 / r = 1.09/.274 = 3.9781 rad/s

ω final = vf / r = 2.99/.274 = 10.9124 rad/s

ωf^2 = ω0^2 + 2αθ

(10.9124)^2 = (3.9781)^2 + 2(.8728)α

α = 59.1 rad/s^2 but this is wrong...What am I doing wrong? A little frustrated here...any help much appreciated!
