Question

An electric ceiling fan is rotating about a fixed axis with an initial angular velocity magnitude of 0.300 rev/s. The magnitude of the angular acceleration is 0.902 rev/s2. Both the the angular velocity and angular accleration are directed counterclockwise. The electric ceiling fan blades form a circle of diameter 0.800 m.

Compute the fan's angular velocity magnitude after time 0.206 ss has passed. Express your answer numerically in revolutions per second.

Through how many revolutions has the blade turned in the time interval 0.206 ss from Part A? Express the number of revolutions numerically.

What is the tangential speed vtvt of a point on the tip of the blade at time tt = 0.206 s? Express your answer numerically in meters per second.

Calculate the magnitude atat of the tangential acceleration of a point on the tip of the blade at time tt = 0.206 s.Express the acceleration numerically in meters per second squared.

Calculate the magnitude arar of the radial (or centripetal) acceleration of the point at the end of the fan blade.
