A wheel of radius 0.50 m rotates, starting from rest, with a constant angular acceleration of 2.0 rad/s² (magnitude only. The wheel rotates about a fixed axis that passes through its center and is perpendicular to the wheel. Consider the following statements about the wheel's motion at t=3.0s.
(i) The angular speed of the wheel is 9.0rad/s.
(ii) The angular speed of the wheel is 6.0rad/s.
(iii) The tangential acceleration (magnitude only) of a point on the wheel's rim is 1.0m/s².
Which of the following is true?
- Only (ii) and (iii) are true.
- Only (i) is true.
- Only (ii) is true.
- Only (iii) is true.
- Only (i) and (iii) are true.
