The angular acceleration of a wheel, as a function of time is a = 5.0 t^2 - 8.5 t, where a is in rad/s^2 and t in seconds. If the wheel starts from rest (θ = 0, ω = 0, at t = 0), determine a formula for (a) the angular velocity ω and (b) the angular position θ, both as a function of time. (c) Evaluate ω and θ at t = 2.0 s.
