    angular acceleration α in rad/s²

      ω = Δθ/Δt = (75–25) rad / 10s = 5 rad/s

    but ω is constant, so α is zero

    but from the answers, you want something else... with units of m/s²

    perhaps:

    linear tangental acceleration, αt

       α = αt/r

    at = rα

    since α = 0, linear tangental acceleration is zero.

    or, do you mean centripetal acceleration ?

    Centripetal acceleration is

    a = Vdθ/dt = ω²r = Vω = V²/r

    a = ω²r  = 5²0.14 = 3.5 m/s²
