Question:

The blade of a fan rotates with angular velocity given by the equation: w(t) = (5-0.8t²) k rad/s).

a) Find the angular displacement in the interval t=0s at=3s.

b) If it is known that the length of the blade is 0.5 m, find the number of complete revolutions that the blade undergoes until it stops for the first time.

c) Can the angular position be found instantaneously?
