A wheel 70 cm in diameter is accelerated from 160 rpm to 300 rpm during 4.0 s.

Find the diameter component and tangential component of the line acceleration of a point at the wheel edge when the wheel is accelerated 2s.

Answer # 1 is Ac = 202.78m / s ^ 2 and At = 1.28m / s ^ 2.

The words used in the question are so unfamiliar that I have difficulty in approaching the problem, so I have asked this question.

The angular acceleration of the wheel was 3.66 rad / s ^ 2, but I do not know how to solve it after that.

Please let me know how I can solve this problem.
