The angular position of a point on the rim of a rotating wheelis given by θ = 9.33t - 3.93t2 + 1.09t3, where θ is in radians andt is in seconds. What are the angular velocities at (a) t = 2.13 sand (b) t = 8.41 s? (c) What is the average angular accelerationfor the time interval that begins at t = 2.13 s and ends at t =8.41 s? What are the instantaneous angular accelerations at (d) thebeginning and (e) the end of this time interval?
