Physics
The blades of a ceiling fan have a radius of 0.380 m and arerotating about a fixed axis with an angular velocity of +1.50rad/s. When the switch on the fan is turned to a higher speed, theblades 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 ablade and
(b) the angle φ between the total acceleration a and thecentripetal acceleration ac?
