The angular position of a point on the rim of a rotating


Question: The angular position of a point on the rim of a rotating wheel isgiven by θ = 4.0t - 3.0t2 +t3, where θ is in radians andt is in seconds.

(a) What is the angular velocity at t= 3 s?

(b) What is the angular velocity at t = 5.0 s?

(c) What is the average angular acceleration for the time intervalthat begins at t = 3 s andends at t = 5.0 s?

(d) What is the instantaneous angular acceleration at the beginningof this time interval?

(e) What is the instantaneous angular acceleration at the end ofthis time interval?
