An electric ceiling fan is rotating about a fixed axis with an initial angular velocity magnitude of 0.250rev/s . The magnitude of the angular acceleration is 0.891rev/s2 . Both the the angular velocity and angular accleration are directed clockwise. The electric ceiling fan blades form a circle of diameter 0.800m .
1. Compute the fan's angular velocity magnitude after time 0.194s has passed. (rev/s)
2. Through how many revolutions has the blade turned in the time interval 0.194s from Part A? (rev)
3. What is the tangential speed vtan(t) of a point on the tip of the blade at time t = 0.194s ? (m/s)
4. What is the magnitude a of the resultant acceleration of a point on the tip of the blade at time t = 0.194s ? (m/s^2)
