If three 1.1 m fan blades are connected to a motor and accelerated uniformly from rest to 58 rpm in 11 minutes.
(a) Determine the angular acceleration of the blades.
(rad/s^2)
(b) Determine the radial and tangential component of the acceleration on a point at the end of one of the blades 2.0 min after the blades started their acceleration.
1) radial (m/s^2)
2) tangential (m/s^2)
