A wheel rotates with a constant angular acceleration of 3.50 rad/s2. The angular speed of the wheel is 2.00 rad/s at t = 0. If the radius of the wheel is doubled, Are the following statements affected? If so, in what way? (Select all that apply.)

(1)The angular speed at t = 2.00 s is the same.
(2) The angle rotated through from t = 0 to t = 2.00 s is smaller.
(3) The angle rotated through from t = 0 to t = 2.00 s is the same.
(4) The angular speed at t = 2.00 s is greater.
(5)The angle rotated through from t = 0 to t = 2.00 s is greater.
(6)The angular speed at t = 2.00 s is smaller.

i think its (4) and (5) but i have no clue...
Thank You
