The blades of a ceiling fan have a radius of 0.380 m and are rotating about a fixed axis with an angular velocity of +1.50 rad/s. When the switch on the fan is turned to a higher speed, the blades acquire an angular acceleration of +2.00 rad/s² . After 0.500s has elapsed since the switch was reset, what is

(a) the total acceleration (in m/s) of a point on the tip of a blade and

(b) the angle φ between the total acceleration a and the centripetal acceleration a_c?
