Question: An electric ceiling fan is rotating about a fixed axis with an initial angular velocity magnitude of 0.210rev/s. The magnitude of the angular acceleration is 0.888rev/s2. Both the angular velocity and angular acceleration are directed clockwise. The electric ceiling fan blades form a circle of diameter 0.700m.
Part A: What is the magnitude a of the resultant acceleration of a point on the tip of the blade at time t = 0.196s?
I need help to find the magnitude of the resultant acceleration of a point on the tip of the blade.
