Topic: Motion with Constant Angular Acceleration

18.) A large ceiling fan has blades of radius 60 cm. When you switch this fan on, it takes 20 s to attain its final steady speed of 1.0 rev/s. Assume a constant angular acceleration.

a.) What is the angular acceleration of the fan?

b.) How many revolutions does it make in the first 20 s?

c.) What is the distance covered by the tip of one blade in the first 20 s?
