The angular position θ of a 0.36-m-diameter flywheel is given by θ = 2.0 t³. (a) Find the θ, in radians and in degrees, at t₁ = 2.0 s and t₂ = 5.0 s. (b) Find the distance that a particle on the flywheel rim moves over the time interval from t₁ = 2.0 s to t₂ = 5.0 s. (c) Find the average angular velocity, in rad/s and in rev/min, over that interval. (d) Find the instantaneous angular velocities at t₁ = 2.0 s and t₂ = 5.0 s.

The angular position of a point on the rim of a rotating wheel is given by θ = 8.79t - 6.38t^2 + 2.10t^3, where θ is in radians and t is in seconds. What are the angular velocities at (a) t = 3.15 s and (b) t = 8.76 s? (c) What is the average angular acceleration for the time interval that begins at t = 3.15 s and ends at t = 8.76 s? What are the instantaneous angular accelerations at (d) the beginning and (e) the end of this time interval?
