Angular velocity is given by:
Average angular acceleration is expresed as:
Instantaneous angular acceleration:
Angular velocity is:
The angular position of a point on the rim of a rotating wheel is given by θ = 4.0 t — 3.0t2 + t3, where θ is in radians and t is in seconds. What are the angular velocities at:
(a) t = 2.0 s and
(b) t = 4.0 s?
c) What is the average angular acceleration for the time interval that begins at t = 2.0 s and ends at t = 4.0 s?
What are the instantaneous angular accelerations at:
(d) the beginning and
(e) the end of this time interval?
